Bought a 99 B4 RSK Twin turbo recently and was doing some reading about them and people get good gains with just little mods and a remap? Just wondering many on here get it done? What's the best to get done ? Best mods to have for a map? Do I need to change ECU can you map the original ecu etc?
Any info would be great :yellowthumb:
