    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.

  • Tony from Tonbridge with a Audi A4 2.5 TDI 163 said:

    I just had to drop you a line and say that I am VERY pleased and IMPRESSED with the chip. Fitting took about 5 mins! The gear changing on the auto is now so SMOOTH you have to watch the rev counter to even notice the change, BRILL (before you would feel it going through the gears). I can also appreciate the extra PERFORMANCE (on the supplied settings). I would be more than happy to spread the word on your chips and look forward to seeing the results on fuel economy. Thank you for this truly great product.

  • Steve from Essex with a Audi A5 3.0 TDI 240 Auto said:

    This is the second car to which I have fitted a Chip Express system, and once again I am absolutely delighted. Engine performance is transformed with a first journey that returned 46MPG over speeds ranging from 40 to motorway speeds. Gear changes are smoother, acceleration fantastic and a general performance that will easily match and exceed any equivalent petrol car on the road. Incredibly easy to fit and once again has proved to be completely hassle free. Having driven diesel cars for the last 25 years, my only regret is that I did not discover this company and what they do until a few years ago. The Chip Express service is second to none. I posted my existing box to them on Thursday and they had it re-programmed and back with me by Saturday morning. So, if your thinking about it, put your worries aside and just get one. You wont regret it!

    Wanted to thank you for your great service, speedy delivery to Australia and simple easy to understand installation instructions. I fitted the chip to my Audi A6 3.0 TDI Quattro last week and what a difference. Much more responsive, smooth and lightening fast now off the mark. Having done 700klms with the chip is looks as though I have reduced fuel consumption by about 10%. Great work, by the way, my friend bought your unit for his Audi TT 2.0 TDI, wow, what a difference as well!

  • Stephen from Essex with a Audi TT 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 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 (using the supplied photo instructions). 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 results: Absolutely incredible! I have left mine at the setting supplied 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!

  • Mark from Victoria, Australia with a Audi Q7 3.0 TDI 240 said:

    I currently have one of your chips which we run on an Audi Q7 3.0 V6 TDI. I have had it for approx 12 months or so, the chip is AWESOME, I have left it on the recommended setting, and the torque is incredible!

  • David from Coaley with a Audi A6 2.5 TDI 180 said:

    The chip arrived the next day and was an easy fit - great instructions. I wrote to you before buying as I was keen to improve economy… anyway, economy is around 38mpg, up from 31.8, so good news! The car pulls really well and changes up much sooner through the gears - perfect.

  • Geoff from Kidderminster with a Audi A6 3.0 TDI 240 said:

    I bought one of your chips for my A6 3.0 TDI Quattro. I am delighted so far with the difference, I only purchased it for the fuel economy. Urban has increased from 25 mpg to between 30 and 31 mpg. On a motorway trip of 110 miles the car returned 45 mpg although this is usually late thirtys rather than in the fourtys. Thank you great product.

  • David from Bridge Of Weir with a Audi Q5 2.0 TDI 170 said:

    Firstly, delivery was absolutely on the button, and within 24 hours of placing the order online, my Audi Q5 was chipped. The fitting procedure was phenomenally simple, and the results were immediately apparent. My fuel economy has drastically improved, from high 30's to mid 40's. Absolutely delighted. New car arrives in November, and the first purchase will be another chip!

  • Mergim from Stockholm, Sweden with a Audi A5 2.0 TDI 143 said:

    Got my chip today and installed it! Works perfectly! I'd rate your service 10/10, super-fast delivery (barely 48 hrs to Sweden), and really easy to install! Sincerely, a really happy customer!

  • Grant from Flat Bush, New Zealand with a Audi Q7 3.0 TDI 245 said:

    I installed the chip in my 2012 Q7. Amazing difference in both power and smoothness. I have had it in the car for about two months and recently took it out to get serviced, really noticed the difference when driving to and from the Audi dealer. Would definitely recommend anyone with a diesel buys one!

  • Calum from Fraserburgh with a Audi A4 2.0 TDI PD 140 said:

    Ordered the unit from yourselves at 2.30 pm on the Thursday, unit arrived first post on Friday and fitted before lunch time. So easy! Already feel the difference in performance and achieved 56mpg at a steady 75mph with cruise control on. Have left standard settings on. Very happy!!

  • Brendan from Hertfordshire with a Audi Q5 3.0 TDI 240 said:

    I first researched such chips when Audi kindly announced the soon to be released SQ5, as they were getting so much more BHP out of the same engine by way of a twin turbo. I looked at various companies, but I am so happy I came across CHIP Express as it has completely transformed my car, both in terms of power and economy. I actually wasn’t that bothered about the economy and was sceptical that (on standard setting, as I have left it) I would increase from 240bhp to 280bhp and also see an improvement in economy, but as soon as the chip was fitted (which took 5 minutes) the car was noticeably more powerful! It also has much smoother and quieter gear changes, especially at slow speeds, which seems crazy in a new car? In “sport” the performance seems monstrous for an SUV, whilst still being smoother and quieter! Economy – now the best bit is the bit I was least bothered about! My economy on daily commutes (short and medium runs) has seen the average go from 27mpg to 33mpg. That means instead of 540 miles from a full tank I’m up to 660 miles! Quite simply this is the best money I have ever spend on any gadget for any car. Even my wife loves it and she fell out with me when I placed my order. I would never have another diesel car without fitting one of these chips and cannot recommend then highly enough.

  • David from Basingstoke with a Audi Q5 3.0 TDI 240 said:

    I ordered a chip for my Audi Q5. I was immediately impresses by the packaging which reminded me of the same quality and attention that Apple employ for products such as their iPhone's. The instructions which included photos of my specific engine made fitting an absolute doddle. And the results? The engine feels much more eager and responsive when you put your foot down as the extra horses and increased torque kick in. It works perfectly with my 7 speed DSG gearbox which is clever enough to change up or down dependant on engine load, and now it seems to select a higher gear at lower speeds than before, less throttle is needed for normal driving which had my average economy edging toward 40mpg (normally 32mpg) for an urban journey of less than 12 miles. Looking forwards to seeing if I can better my 43mpg on a run from Hampshire to Cornwall in a few weeks. Think I'll leave the chip on the supplied setting as so far it's giving me everything I'd hoped for.

  • Timothy from Stoke On Trent with a Audi A4 3.0 TDI 233 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!

  • Paul from Newcastle Upon Tyne with a Audi Q5 2.0 TDI DSG 170 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. 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!

  • 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

  • Ryan from Cape Town, South Africa with a Audi A3 2.0 140 said:

    WOW what a difference! The first thing I noticed was that the revs in 1st gear where much higher and free flowing and then in all the others too. I could only drive in traffic yesterday, but still felt a huge difference with the car wanting to take off - easy tiger! There is a much smoother transition between the gears and much less turbo lag. Today I was on the open road, and WOW again. Great product!
