Neil from Isleworth with a Audi A4 1.9 TDI 130 said:

I am writing to express how impressive your tuning chips are, I am particularly impressed with the smoothness of the power delivery. I have tried 2 previous different tuning boxes on my Audi A4 1.9 TDI 130 and sent them both back, but yours I have to say is the best one by far - thanks!!! p.s I have already recommended this to my friends and family.

James from Callington with a Land Rover TDV6 said:

May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery 3. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The Chip Express system does not show any evidence of this and is equal to the likes of an ECU remap from Superchips (which I have also had done before) for smoothness and noticeable power gains but for a great deal less money. This would be the only diesel tuning product I would recommend.

Keith from Barkestone Le Vale with a Honda 2.2i CTDI said:

Received the kit for my Honda CR-V this morning - less than 24 hours after I ordered it. Simple, clear instructions. I spent 5 minutes reading through the instructions and it took me just under 10 minutes from start to finish to install the system - and I have no mechanical knowledge or experience, so if I can do it anyone can. Left the setting on the pre-configured mark and went for a test drive and WOW! Immediate and noticeable increase in power and especially torque. Couldn\'t resist tweaking it so increased to the next level and went for another test drive. DOUBLE WOW! I am amazed! I think I shall leave it on this setting - it definitely doesn\'t need any more! All in all I can recommend this system - it does exactly what it says it will do and it is a simple 10 minute job to install.

Peter from UK with a Renault Scenic 1.9 dCi 130 said:

I'd had my Renault Scenic DCi 130 for 3 years and was getting fed up with its performance and general sluggishness. Got the tuning box from your good selves, fitted it in the dark in about 10 min. What a difference! Makes me smile just thinking back to that first drive. The box has been on the car for about 3 months so far. Economy is up by around 15%. General driveability is excellent on standard setting, mid-range punch is a revelation.

Ian from Dereham with a Chrysler Voyager RT 2.8 CRD 163 said:

You will not get a much simpler kit to fit, the performance and MPG gain is well worth the outlay. It's like driving a different vehicle, so much more torque lower down the rev range - a must for any Voyager RT owner.

Hugh from Ashtead with a BMW 520d 163 said:

Am very pleased with the product bought for my BMW 520d. The claims you make are all borne out by the results I am getting. A really good car is even better as a result. Thank you also for your prompt service.

Leighton from Nottingham with a Mitsubishi Shogun 2.5 TD 115 said:

Just wanted to send a bit of feedback regarding the unit I fitted to my Shogun Sport 2.5 TD. The unit was ordered around 2:30 one afternoon and was delivered at 7:30am the next morning, absolutely fantastic service! I fitted the unit on my lunch break at work and the installation was incredibly simple. The difference is fantastic, the car revs smoother and higher, no need to rev the engine a little bit whilst pulling away now as it feels like the power is instantly available from a standstill. There is definitely a lot more power and torque in every gear and the cars performance has been totally transformed. I honestly can not fault the unit or the service that Chip Express have provided, thanks!

Andrew from Southwell with a VW Touareg 3.0 V6 TDI said:

Can I say what a brilliant piece of kit the tuning box is. It resolved the flat spot that seems to come with the engine's standard set up and gives a great surge of extra power, and yet I return about 2mpg better fuel economy. Brilliant!!

Matthew with a Volvo V40 2.0d 136 said:

Volvo 2.0d 2005. I had a box for my Golf Mk4 GTI 150PD from Van Aaken and it was good. I have just gone from a 300bhp Skyline to this diesel Volvo and was sad to miss the power. I looked about and bought the Chip Express device. It really is amazing. My Volvo would give my old Golf a run for its money. Mpg standard was 44mpg (driving normally) and is now 52mpg! Awesome Product!

Pedro from Colne, Lancashire with a Alfa Romeo GT 1.9 JTDm said:

Since I installed your product the mpg improvement and the ease to drive (due to better torque and increased power) were immediate. Thank you very much for giving me such performance gains without changing the car!

Dave from Plymouth with a Toyota Corolla 2.0 D-4D 90 said:

Just to say how pleased I am with the product, I went from Plymouth to Portsmouth, the mpg before fitting the Chip Express device was 46.8 mpg - we made 60 mpg on the 170 mile trip. We did some short runs while there and a return trip yesterday, we averaged 58.2mpg on the 425 miles covered. Many Thanks! A Very Happy Customer.

Benjamin from Midhurst with a Mercedes B180 CDI 109 said:

I have just fitted one of your chips to the above vehicle, and I have to say that the improvement to both mid range performance and MPG has been amazing. Both my partner and I just cannot see why Mercedes do not run with these devices as standard. It makes a pretty gutless and dull car so much better. We did not, of course buy this car for its performance, my partner needed an automatic due to her bad knee, however both of us were surprised quite how dull it was to drive. I had known about these devices for some time but had not experienced them 1st hand. I have to say that it transforms the car into just what we want. Money well spent, thank you.

Nick from Tamworth with a VW Jetta 1.9 TDI (105) said:

We recently bought a caravan and collected it with our car but when towing realised we needed more power, a friend told us to use 'Chip Express'. I bought one and fitted it last week, went for a test drive and 'WOW' - the power is amazing now. We towed the caravan earlier today and noticed it was much easier to pull and the fuel economy was much better, when we picked it up we got 33mpg but now we're getting 40mpg. We are very impressed, especially as we ordered the box at 4:30pm on Friday and received it Saturday morning!!

Timothy from Stoke On Trent with a AUDI A4 3.0 TDI said:

I ordered my Chip Express for my 2007 AUDI A4 3.0 TDI on Tuesday afternoon, to my surprise it arrived the next day at 08.30; fantastic service. I fitted it that evening in less than 5 minutes thanks to the easy and accurate instructions and photo's. The difference is staggering; the torque is huge giving blistering performance with no black smoke. Great product!

David from Darlington with a BMW 320d 177 PS said:

Wow, I just cannot believe the difference. It is like driving the 3lt diesel with 50mpg+. I don't know how you have managed it and it shows that for whatever reason BMW are not getting the best out this engine in std tune. Thanks very much and have recommended to all my diesel driving friends.

David from Woodbridge with a Chrysler 300C 3.0 CRD 218 said:

Thank you for prompt delivery. Spent some time reading my instructions then went ahead and fitted the chip to my Chrysler 300 CRD... the power now feeds in strongly from1500rpm and use of kick down on the auto is not really needed. Your chip has completely transformed the car into a refined high speed cruiser. I love it, thank you very much.

Robin from South Yorkshire with a BMW 30d xDrive X6 said:

I know that you have a considerable number of happy customers but I would just like to add to that growing number! The ease of fitting was incredible (literally minutes as you promised!) and the resulting improvement in the engines low end performance is worth every penny.

Barry (Algarve region, Portugal) with a Peugeot 407 SW 1.6 HDI 109 said:

Just to let you know I've fitted the unit to my Peugeot 407 SW 1.6 down here in the Algarve, where it's warm and sunny, and, as with our Volvo D5 system, simple to fit, the instructions are excellent and it runs beautifully, much better response, heaps more go and it looks as if the economy, already good, is even better. Thanks again.

Paul from Newcastle Upon Tyne with a Audi Q5 2.0 TDI 170 PS said:

I purchased a chip from you early last month. Sadly I fell and broke my ankle the day after I fitted it so I couldn't drive for 5 weeks. I would just like to say Wow! It has totally transformed the car (Audi Q5 2.0Tdi DSG auto). In particular the slow speed driving is much smoother, the car does not hunt for gears as much and the economy is amazing. I saw 44.5mpg on my 35 mile commute to work yesterday. The best money I've ever spent on a car!

William from Dublin with a Nissan X-Trail 2.0 dCi 173 said:

Just fitted the new box you sent me. What a difference it has made... the power is unbelievable, acceleration is better, mid-range it is so quick no matter what gear you're in and top speed is much improved, fuel consumption is slightly sore when you use full throttle (to be expected), but when driven normally I could not believe how much more economical it now is! I will be recommending it to my friends. I would like to thank you for the assistance you gave me when I was fitting the box... I am very impressed!

Michael from Northwich with a Vauxhall Insignia 2.0 CDTi 160 said:

Hi guys it's me again with a red face. Here's a good tip - don't try a fit a chip when it's freezing cold and ice on the car and your fingers are as flexible as lead pipes. Go for a run in the car warm it up, leave it 5 minutes and have a cup of good old tea warm the hands and hey presto it fits first time. Just been for a run in it and wow very impressive, it sounds quieter and feels smoother and the performance is terrific... Well done guys!

John from Ashton Keynes with a BMW 335d said:

Just a quick note to say many thanks for the prompt delivery. I fitted the device this afternoon and am very pleased indeed with the results - as you said, the throttle response is much more linear and consequently the car is significantly easier to drive. My wife has just been out for a drive and is also delighted with the results, so many thanks.

Adrian from Farnworth with a C5 2.0 HDI said:

I recently fitted a tuning box from Chip Express. I have since done over 4000 miles. What a difference this little box has made... I am averaging 50.4 mpg at motorway speeds, with greatly improved acceleration. Well done everybody at Chip Express... worth every penny!

Morgan from Malaga with a Hilux 2.5 D-4D said:

My vehicle is 102 HP 2004 Toyota Hilux 2.5 D-4D with 50,000 miles running 31 10/50 15 tyres. Your chip has smoothened out the power very well! It now pulls evenly through the rev range with no excess fuel knock or injector rattle on overrun, no blacking on power from the exhaust. The increased torque means less loss of speed on hills but also you notice the fact that you don't need to change down as much on mountain roads. When I tested this Toyota for the car magazines in 2004 my main gripe was that the long gear ratios were not suited to the short power band on the 2.5 D-4D... but your chip does what the manufacturers should have done by making the engine pull from lower in the rev range... on these vehicles that is a welcomed change to its original characteristics!

Greg from Crediton with a Land Rover TD5 said:

Firstly, many thanks for an excellent product. It arrived the next day in perfect condition. I fitted the chip myself with a little assurance from one of your technicians. After road testing I can confirm all flat spots have now been replaced with silky smooth torque! I would recommend your product to anyone. Thanks again.

Don from Auckland with a VW Golf 1.9 TDI 105 DSG said:

Last Saturday I fitted my new Chip Express system and all I can say is WOW!! It measured up to every aspect that you promoted it on as regards the upgrade in performance. It is measurably smoother, in fact quieter, far more torque, and changes gears much more rapidly... it is very quick now! Cheers.

John from Grantham with a Ford MondeoTDCi said:

Just a quick note to thank you for the swift delivery of your CHIP Express unit. I couldn't believe it arrived so quickly and also how easy it was to install thanks to the clear instructions. The performance and sheer driveability has been increased 100% with no side effects - it feels like a completely different and much newer car with smooth delivery of power right across the rev range, amazing considering it is six years old and has covered almost 80,000 miles. I will have no hesitation in recommending your product to my friends. Many, many thanks.

Chris from Essex with a Audi A4 2.0 143 TDI CR said:

Hi there, just wanted to say thanks and how pleased I am with my purchase. At the moment the box is still set up on your standard settings, the change from standard is amazing, loads more torque, better throttle response, increased MPG and a joy to drive. Once again many thanks

Ian from Darwen with a Volvo 2.4 D5 said:

Having recently bought you product I can tell you this has transformed my vehicle... better MPG, I achieved 32mpg whilst towing my 1500kg caravan. I took the vehicle for its MOT and passed the emission test with flying colours. A better CAR ALL ROUND!

Paul from Oxfordshire with a Toyota 2.5 D-4D said:

Just a quick note to let you know that your product has made a huge difference to the performance of the vehicle. It has made the power so much smoother over the entire rev range, given added thump when needed, and the economy has noticeably improved after a long run over known mileage this past weekend. Really impressed with the chip and was surprised how simple it was to install, especially as I hate dealing with electrics of any sort being a 'mechanical engineer'. Those sparky things are well left alone usually for us types. Thanks to everyone for their help and advice and prompt service.

Jeffrey from Co. Antrim with a VW Scirocco 2.0 140 said:

I recently bought a tuning chip for my 09 VW Scirocco, the power gains were fantastic and I was very impressed that I could so easily adjust the power setting by myself. This is alone makes Chip Express product unique from any other I have came across!Standard I was getting at best 48mpg but with this box I now achieve over 60mpg! The customer service if brilliant too! I would recommend Chip Express to anyone and already have recommended them to friends and family.

Steve from Southampton with a Mercedes CDI 2.2 said:

First surprise: Having ordered my unit around 4pm on Friday afternoon, I was most surprised and very pleased to receive it first thing on Saturday morning. Second surprise: Ease of fitting. Third Surprise: The overall difference it has made to the car. I own a Mercedes C200 CDI and have always felt that Mercedes got it wrong with this model; however I bought it and am stuck with for the foreseeable future. Your unit has turned it into what it should be, it is now smoother, quieter, responds better and the difference in fuel economy is nothing short of outstanding. Today on a regular trip from Southampton to North London and back I saw the mpg raise from 42.1mpg (average) to 51.2mpg (overall average for the round trip) and apart from road works (M3 & M25) and typical M25 hold ups, I was driving at normal motorway speed (outside lane with flow of traffic).I was that impressed I even stopped in the services on the way back and took a photo of the trip computer display. It was showing the following: From Start 152ml / Av speed 45mph/ 51.0mpg!

Stephen from Essex with a Audi 2.0 TDI 170 said:

Having spent a lot of money on my new TT I was somewhat nervous about fitting the chip...I contacted Chip Express ... the technician I spoke to laid my fears to rest...although entirely willing to fit the chip for me (at a cost of £50) assured me that this was not necessary and offered to talk me through the process by phone.As it was raining heavily I declined. The following day and still being a little concerned regarding my technical ability my friend fitted it for me.The task was indeed extremely simple and had I pushed my doubts away would have managed with no hassle. It is as simple as Chip Express tell you it is.So now to the result: Absolutely incredible! I have left mine at the setting installed by the company and the results are amazing.Throttle is crisp and responsive, gear changes seem smoother.Absolutely no engine lag... mid range it pulls like a steam train...gear changes do indeed arrive sooner and as claimed there is much more speed variance available with no engine labour in the higher gears, so less changing down.Absolutely chuffed to bits. I made the decision to go with a diesel based on economy... but now also have the performance of the petrol version. Fantastic!

Alan from Coventry with a Suzuki 1.3DDIS said:

Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.

Brenton, from Canberra (Australia) with a Peugeot 2.0 HDI said:

Just got back from my first test drive, post-fitting my new Chip Express. Wow! Not that you didn't warn me! Your other customers weren't exaggerating! Yes, yes, yes! Smoother: not even one bolt rattling in the bucket; quicker, smoother change-ups using then previously-irrelevant tiptronic; and that awesome tow from < 1000rpm! More impressed than I had expected, even from your website reviews. Now, to take on my mouthy accountant's Cooper S! I can hardly wait to get it on the freeway to Sydney for a real spin! Now all I need is a radar-detector! Well done, Chip Express!

Dave from Leatherhead with a Ford 2.2 TDCI 175 said:

I have had the system installed for a couple of days now and am amazed at the difference it makes to the driveability of what was already a very nice car to drive, and economy on my route to work has increased from 40 to 47 mpg... a fantastic product that does exactly what it promises to do.

Richard from Southwater.com with a Volvo Penta D3 190 said:

We have fitted one of your systems on Friday to a D3 190. We went on sea trials with the owner and (VODIA) Volvo diagnostics installed. No problems and noticed a much smoother acceleration. Also the engine ran much sweeter and got to its top speed quicker.

Richard from Washington USA with a Mercedes 3.0 CDI said:

I purchased an identical chip from you about 5 months ago after being less than impressed with my recent Mercedes R320 CDI performance. Well your chip made THE difference! I purchased a second R320 about 4 hours ago and am ordering a chip for that car before I even get the car next week! My brother-in-law also will be purchasing one from you in the near future! Thank you so much! FINALLY a device the delivers as promised.

Daniel from Co. Limerick Ireland with a Ford 2.0 TDCI said:

Just here to say I got my chip today. It is true what they say; my car was nice to drive but now it's magic! Much quicker and changing up gears faster. Thanks Chip Express, keep up the good work!

Dennis from USA with a Mercedes ML320 BlueTec said:

I just arrived back from a long trip... the results are simply amazing - far better than my best expectations. I got as high as 37 mpg on one segment of 250 miles on a four lane road and 36.7 on a 740 mile leg. Overall, I drove over 2500 miles and averaged 33.7 mpg which includes a lot or city driving. Driveability is unchanged or if anything, improved. Before, there was a turbo lag that was annoying at times. Thanks again for your help. Your device is superb.

David from Ryton with a Golf PD140 TDI said:

The chip is amazing! Just plugged it in this afternoon. The torque is unbelivable, so is the power. I had to settle for a Golf GTTDI instead of a GTI due to insurance and petrol costs, but this chip has just made it better than any GTI. My so called 140PS Golf is now one not to be messed with. Thanks Chip Express!

Danny from Ballymoney with a Suzuki Vitara 1.9 DDiS 129 said:

I ordered a tuning unit last night and received it this morning at 10am. I have fitted it and the results are as you specified. The Vitara 1.9 DDiS runs beautifully and the poor torque at low revs has gone making the vehicle a pleasure to drive. Thank you very much for a great service and a brilliant product. It really does work!

Graeme from Galsgow with a Jaguar X-Type 2.2 155 said:

I fitted the Chip Express unit a few weeks ago, and have just had the car on an 800 mile round trip, Glasgow-Cardiff. Genuine 50mpg! Ran beautifully, with noticeably better acceleration, overtaking at 70 in 6th gear effortless, due to immense torque. I'm delighted. Thanks for a great product.

Eden from Auckland NZ with a Mercedes GL350 CDI 224 Blue Efficiency said:

I can not believe the difference, I was going to get rid off my new 2010 Benz GL, once a slug... now its a weapon, its unreal!! I also have a new BMW M3 but now my Benz is my favorite toy, cheers!

Derrick from Pontypridd with a Alfa Romeo GT 1.9 JTD 150 16V said:

The more I drive my Alfa the more I am pleased with your product. I recently drove to Newcastle, a round trip of over 700 miles. On my return I had achieved an average of 58.4 MPG. Fantastic! Thank you once again.
