Anthony ,Mercedes ML 270 CDI

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....

Nigel ,VW Golf 2.0 TDI

After fitting had laptop tune. Tested on Tunit rolling road and tested against Golf 2.0TDi 170bhp by VW Driver mag. More power and torque than the 170 plus would pull in 6th from 1000rpm. This is now a very quick car delivering 50+ average mpg.(or more if you take off the lead boot)
