Thanks for all your help on Monday, I didn?t appreciate the difference in my car until yesterday. Getting into it after not driving for 24 hours was a revelation. Cold starting did not produce the usual black smoke, there was no hesitation when moving off form standstill and the throttle response was much quicker with VERY smooth acceleration. So smooth that my wife commented on it. The improvement to torque at low revs means that the car will trickle along in 3rd gear without throttle, even up a slight incline! All in all Tunit is worth every penny.

I have always had performance upgrade on all my cars history butthe Mercedes Diesel was my first. Having visited the motorshow and did some research tunit offered value for money and true figures to what is claimed. There was a huge difference when I fitted the Tunit kit that the egineer who installed it was very impressed. Here is an expample We drove on a stretch of road standard form and we hit 74mph at a marked point.After installing Tunit the same point we hit 89mph as the tourqe band was huge. Im pleased and well happy still reliable and savings on fuel agerage mpg gone up by 5-8mpg more.A good and worthwhile investment....
