So whilst scrolling through my facebook feed i see a lot of dyno companies and some have had vw polos or golfs running and they claim to have crackle/ over run enabled. Is it possible to get this on my leon mk3 1.8tsi when i take it to get stage 1. Has anyone done this and what are the affects both good and bad? Such as excess wear on components or cats
