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....

Gareth ,Ford Fiesta 1.4 TDCi

The tunit has increased the power and fuel consumption of my Fiesta by at least 10%. I used to get 58 mpg and have recorded 65 mpg when drivng steady for a whole tank. This was done on dual-carriageways into work.
