So for yet more power, I'm thinking only S1 needs to be tweaked...but wondering how much more.
When I talked to Racechip support about the 2 switches,they replied for a Petrol turbo charged engine,like the N55,do not change the setting on S1.For a diesel engine it's another story.You also should not go "willy-nilly" with that screwdriver without talking to them first.Makes sense to me,by increasing the turbo boost you put more stress on the engine.I provided for you a video file name,which should be easy to find with Google.It's been released by the Racechip people to explain the tweaking of S2.
