Yeah, remapping your car, who does that? I mean honestly, if you want 300bhp go and buy a car with it already.
Ah, remapping is different, just like adding
aftermarket wheels/body pieces etc. A remap is taking the engine from OEM to something else. Thats ok; you're not trying to make the car like another in the range (I know you can remap a GTI to something like ED35 or R etc).
To go completely against my argument; It's your car. If you want to do it, then do it.
