Got my new unit, brilliant as normal!

Niel , Audi A3 TDI

From knowing little about diesel tuning I knew my car was more capable, a friend recommended tunit. One phone call convinced me it is a quality product, I collected my box the same afternoon were I was taken through the product install and even shown were to locate the box on my car. The service was fantastic and even before fitting the tunit box I left with a smile and now an even bigger one with the difference it has made to my car!! thanks
