Rob from Watford with a Mazda 6 MK3 2.2 SKYACTIV-D 150 said: Just had my chip fitted to my 2015 Mazda 6 150 Sport and it has exceeded well all expectations. It has been fitted on the factory supplied setting and provides excellent acceleration and torque. I will settle for factory setting for now. Impressed!
Brian from Crawley Down with a Mazda 6 MK2 2.2D 180 said: I purchased this in Sept '14 but have waited a few months before writing a review. It's simply brilliant, reasons? (1) Improved fuel consumption under normal driving conditions (2) Noticable improved flexibilty in gears especially at slower speeds (3) Smoother engine (4) Big improvement in performance which, when used doesn't use a huge amount of extra fuel (5) Much improved torque. I got a professional to fit mine (he knew Chip Express products well) and we initially used the default mid-way setting. After trials we settled on the default setting but fine tuned it to maximum. This gave a big improvement on the edge of Traction Control kicking in so there's no stress, just a big overall improvement. Our 2011 Mazda 6 Sport (180) was quite quick anyway but this has made all the difference - more fun, even easier to drive and better fuel consumption. The car feels better for it. I therefore have no hesitation in recommeding it. I only wish I'd bought it sooner. Only one tiny downside is it does confuse the average MPG indicator but having carefully checked it, it shows 4 MPG less than is true. For example - shows 46 but is actually 50 - no complaints! Just buy one!
Glenn from Saundersfoot with a Mazda CX-7 2.2D 173 said: The chip arrived the next day and was easy to fit after following the instructions. Although there was a difference on the standard setting after "tweaking" or fine tuning the car has all the performance I require. The increase in power especially midrange in 4th/5th and even 6th gear is considerable. As to saving fuel, I'm enjoying the increase in power at the moment, but I can see that I will not have to keep changing down so much. Cheers!
Michael from Liverpool with a Mazda CX-5 2.2 SKYACTIV-​D 175 said: The chip on my 2013 Mazda CX-5 gave me increased power, torque and fuel economy which was really helpful when towing. The chip is also very easy to fit and remove, I've been using it now for nearly 5 years! Miles of smiles!
Steve from Port Augusta, Australia with a Mazda BT-50 MK1 3.0D 156 said: Fitted the power chip today, well I am converted! Standard settings as supplied were perfect, lots of low end grunt for towing, great midrange which extends beyond what you actually need. No more turbo lag, now super responsive from 1000 rpm, this is much better for moving trailers or retrieving boats etc, the clutch no longer needs to be slipped to get rpm up to pull the load initially. This is the best upgrade I have done on any vehicle, money well spent! Please submit my feedback so others may benefit. Thanks for such a great product!
Stefan from Reith bei Seefeld, Austria with a Mazda CX-5 2.2 SKYACTIV-​D 175 said: A very simple and clean "installation" - done in 5 minutes with no tools necessary. Smooth increased performance, ideal for when driving in the mountains here. Keep up your great customer service and the excellent product quality! FOLLOW UP: I am really enjoying the CHIP Express tuning on my other two cars now, a Fiat Doblo 2.0 Multijet 135 and a VW Caddy 2.0 TDI 150. Great and smooth performance yet again!
David from Ramsey with a Mazda CX-5 2.2 SKYACTIV-D said: Excellent service, easy to use website. Pleasure to do business with from start to finish. Module professionally built and very easy to fit!

What others are saying...

“Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! Thank you.”

“I was a sceptic at first, then after reading the experiences others had been through I decided to give it a go. I bought a new 1.7 CRDI Sportage, not the 2ltr purely for better fuel figures. Whilst this engine pulls very well in standard form, and was returning 44-45mpg even during the first 500 miles I had to go down the CHIP Express route. Well, there is absolutely no point in forking out the extra 2 grand for the 2 litre model when you can get the 1.7 and spend much less to get 2 litre power figures. Excuse the cliché’s, but this car is transformed and by a big margin too. From what I can remember about my 2 litre test drive, my 1.7 now pulls better than the 2 litre version. The low-down grunt is remarkable and pulls like the proverbial train. Fitting took minutes and was effortless, the box was kept on factory settings, I feel there is no need to mess with it. Needless to say I am now a very happy boy and would without question take this route again. I would recommend this to any diesel Sportage owner. Many, many thanks for a remarkable product and a customer service that is rare in this country!”

“A friend recommended one of your "gadgets" a year ago and being not-very-techno (but Scottish and keen to save money!) I bought one. The gizmo has TRANSFORMED the performance of my Land Rover Freelander 2 TD4 AND improved the fuel economy by a genuine 15%; so much so that I have bought another one for our Freelander 2 SD4 which is now a REAL Q-car! (And of course saves fuel...) I have never written a review before (though strangely I do read them and take notice of them, whilst half-believing that they are written by the owner's chums!) so to have made me pick up pen & paper so to speak - I MUST be delighted! Thanks for making technology so simple and so successful!”

Land Rover Freelander (2) SD4 190

“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.”

“May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. 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 (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.”

Land Rover Discovery (3) 2.7 TDV6 190

“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”
