REVIEWS

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)

Tony , Mitsubishi L200 animal

Immediately saw a fuel efficiency increase of 4mpg. I have not changed way I drive and now I have much more acceleration under my right foot - comes in handy. I now will not be selling my vehicle for another year as its like having a new truck!
