REVIEWS

Mark ,Ford Mondeo 2.0 TDCi

Not only the fuel saving but the car is smoother to drive and has more power through all the gear range.

Martin ,VW Jetta 2.0 TDI CR 140

Hi Rik, I got the Tunit box this morning as you said and fitted it in ten minutes! Brilliant results, superb fuelling and smooth power delivery. The car really pulls harder in the higher gears and is lovely to drive. I drove a 2000 mile road trip and on average i was getting 54.3 MPG, that is a massive improvement from what i was getting before. Very pleased and your service was top notch. Once again many thanks, a fantastic product. Best Regards, Martin Macqueen.
