Since you've got upgraded turbos, IMO it'd be a good idea to get a custom tune from somebody like Ken at Wedge, Motiv, etc.
I live in Milwaukee and work in Tosa, what color is your 135i? I've seen a handful around the area recently.
Yes I was thinking of going with Trebila, he has a lot of great reviews on N54tech.com.
My 135i is white, looks completely stock right now minus blackline tail lights and black grills... Its a sleeper, ha
