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

John ,Nissan Navara 2.5 dCI D40

I need a large vehicle to transport me and my heavy shooting kit to competitions all over Europe. With fuel costs the way they are, economy on a day to day basis will always be a problem. But my Navara always does in excess of 30mpg with the Tunit fitted. The more I travel, the more I save. I once followed a Porsche Caynne for several miles in Germany on the autobahn. He slowed down at his exit to have a look at what had kept pace with him! So no complaints about performance either.
