Hi , Firstly I hope this is in the right section please move if I have posted it in the wrong one
I was in the hair dressers this morning and listening to a lad go on about his 266 bhp map he had put on his 55 plate GTi , He claims the car is std stock car and has gained nearly 70 bhp , is this likely or the guy who sold him the map being a little bit bold with his figures, I realise 266bhp is easy enough but just by a map ? and nothing else this must be near the top from a stock . Any advice guys
