John from Stoke-on-Trent with a Mercedes ML270 CDI Auto 163 said:We bought one of the units for our Mercedes ML about 4 years ago. It has made a noticeable difference to the performance - the car always seemed to under-perform for its size before it was fitted and this has improved it considerably, thank you.
Ervin from Waltham Cross with a Mercedes ML-Class ML270 CDI 163 said:I want to take this opportunity and thank you for such a great product and service. It was so easy to install and made a HUGE difference to the performance and economy of my ML270. I am now moving to a ML350 and I am sure it will work just as well, thanks again, I'll keep recommending you!
Mike from Fairfield, United States with a Mercedes ML350 CDI BlueTEC 211 said:Just wanted to let you know the chip arrived for my 2010 Mercedes ML350 diesel a couple of weeks ago. I installed it last week, and the results are exceptional! In particular, I had occasion to make a long highway drive two weeks ago (prior to the chip) I got 26.8 mpg on the trip of 900 miles, mostly on the cruise control at 75 mph. I installed the chip last week, and made the exact same drive, same highway, same weather, except at mostly 80 mph on the cruise control. I averaged 31.05 mpg on the second trip – an increase of over four miles per gallon, at a higher speed. I have also experienced a substantial improvement in acceleration, though I don’t have a baseline for comparison. At 73 years old, I don’t do much street racing any more… but, there was this guy with a Mitsubishi Eclipse the other day… Anyway, I just wanted to let you know the chip really did what it is supposed to do. Extremely impressive.
Rod from Wickford with a Mercedes ML350 CDI 231 Blue Efficiency said:I purchased my chip unit in September 2009 primarily for the increase in torque it gives for towing our then new caravan. It was a revelation! Not only did it make for a safer more comfortable drive, the extra fuel economy is very handy when towing. Clearly, when not towing the difference in power and fuel economy is even more impressive. Initial acceleration has a much better response, crisper, sharper again making for a safer vehicle, particularly when exiting round a bouts in the busy periods of high traffic volumes. Powering on (there safe to do so) is remarkable, coupled with the huge difference in the mid range it makes for a true sporting experience. Such has been my experience over the last 5 years that I have had the chip re-programmed by CHIP Express, who I have to say have been really excellent and very efficient with the service, and with the new leads and instructions supplied I will be fitting to our 2011 ML350 Blue Efficiency very shortly. Whilst a more powerful V6 231 bhp CDI engine, I expect, relatively speaking, a similar transformation and experience. 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!”

“I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!”

“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!”

“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.”

“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.”

“As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.”
