Feedback from our Mercedes ML-Class customers:

  • 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!

    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.

    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.

  • Dennis from USA with a Mercedes ML320 BlueTEC 215 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.
