Audi TT 2.0 TDI Roadster
Have driven this car for three years with no real complaints, as a small car it moved well. Now with the pro diesel chip it moves VERY well. Noticable acceleration, improved MPG and a smoother automatic gear change. go get one today.

Vauxhall Insignia CDTi 160
I am sure I am not the only one hesitant in using these products. Finally took the plunge a month ago and fitted it, easy to do leaving it on factory setting 3 initially. I have slowly been turning up the settings up to 6. On this setting the car feels fantastic, the acceleration is noticeably better, mega smooth through the rev range, I do not have to change down gear as much because the torque is there, massive increase in oomph, it feels like a different car.
I have not had chance to fully compare the mpg but at the moment the on board computer is giving a slight increase in economy. However, it’s the extra power which makes this product worth every penny for me.
There are still a number of settings to go (16 in total) and I will continue to increase it until I get a good balance of power and economy.

Prior to buying this I was thinking of selling the car. Not anymore!
