Ive just bought a pd150 leon it has a k&n pannel filter and pulls really really well but the former owner said it wasnt mapped. im really really impressed with how it goes feel like the cupra r i just sold. is there anyway at all i can tell its mapped other than a rolling road? im sure it must be i cant see it being able to go any better than it does.
any advice would be great thanks
