What's the best software upgrade/Chip to give my 330i some more grunt. Currently I have dinan intake, fuel management, and exhaust. that's suppose to be 240ish at the crank and it sure doesnt feel like it.
That shark chip adds a whole 3hp at the wheels, so i dont want that crap. Suggestions please, and from 330 owners only too please. I hear a lot of 323 people saying they can get like 15+hp, but i own a 330
Oh PLEASE include the brand of uprgade and if you can a direct link so i can check it out. its hard to find good bmw parts resources in google, they all seem to be the same site just different colors
