329i sounds good lol maybe we should just put that onto the car after getting it done.. jk..
So can I just to make sure one more time (sry..) after getting the manifold it will gain about 8hp and I can still keep the powerbox? And then after the 330 software it will be getting about the same as the 330 and if I get a tuned software then it will be like making 260-270hp? And with the 330 software or the tuned ones the powerbox will not work right?
just want to make sure I didnt get it wrong..
