Feedback From Our Mercedes E-Class Customers

Leigh from Taunton with a Mercedes E-Class W212 E250 CDI BlueTEC Facelift 204 said: I have a 2015 Mercedes E250 CDI Cabriolet and recently fitted the chip. It took minutes to fit the chip itself and a further few mins of fettling to find the best place to stow the item, all in all a very easy solution. I bought the chip for the extra performance, more torque than power, as opposed to economy gains, and it has delivered it in spades. I took my car out for a spin prior to fitting then again on the same road post fitting and I could feel the difference instantly and everywhere. I highly recommend this product for the grin factor, the economy gains will come as a result of the chip which to me is just a bonus.
Rick from Macclesfield with a Mercedes E-Class E350 CDI 265 said: Thank you for an exemplary service and rapid turnaround. I have to say that the courtesy and quality of service I have experienced over the years should be an example to any company wanting to succeed in business. Many times I have been frustrated and hugely disappointed when addressing a company through their "Customer Service Department", usually, the bigger the company, the worse service you receive. Dealing with Chip Express is definitely a breath of fresh air!
Andy from Norwich with a Mercedes E250 W212 CDI Blue Effieicency 204 said: Many thanks for your excellent and prompt service. Had bought a chip for my Vito 120 V6 which I found made a great family van into a fantastic powerful autobahn cruiser. Fuel returns were up by 4 to 5 mpg but with better performance. Now had chip altered by yourselves to fit onto my E250 cabriolet. Very easy to install. Fuel returns about 7 mpg more after fitting with an increase in power and pulling in gear rather than changing down. Will not hesitate to have chip altered for next car. A very happy client!
John from Beaminster with a Mercedes E-Class W211 E220 CDI 170 said: Test run before fitting, 38.4 mpg. After fitting, same run in exactly same time, 42.0 mpg. Throttle response much better, engine much smoother. As a marine engineer (retired) with over 40 years running power plants up to 40,000 bhp I know when a diesel sounds just spot on! During next 6 days car traveled 890 miles, returning 46.4 mpg. On motorways at steady true 70mph mpg was 50. These figures and acceleration are an astonishing improvement, far better than anything achieved "before chip".

“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!!!”

“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!”

“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.”

“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.”

“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.”
