REVIEWS

Graham ,Audi Q7 3.0 TDI V6

The Tunit fitted and working well. Additional power great but now getting 33 mpg versus the 25 mpg that I was getting. I originally left the setting at the default 5 and was getting about 29mpg, I thought by moving to 7, I would have increased power but reduced mpg, however the opposite has happened. I fitted the unit myself in the end, it was very simple to do.

Rod,Audi A6 1.9 TDI

A fantastic product. As a taxi owner it saves me on fuel but also makes the car easier to drive with less gear changing because of the extra torque
