A couple of years ago I had a Golf Tdi which I chiptuned. It was easy enough, since there was just a small plug to be installed between motor electronic and motor: Plug and play in virtually no time. It could easily be removed, if necessary and gave the car a bit more power without damaging the engine or shortening it's life span. I have a Touareg R5 Tdi now and would like to give him a bit more kick. Has anybody experience with chip tuning on this car and can tell me, if it is equally easy to install and harmless for the engine? Any specific tuning kit you can recommend?
