Hey everyone, I am a recent 128i n52 owner and have been lurking on this site and a few others for some time now. I just purchased a used 128i after owning an E46 and before that an E36.
But enough about the past and on to my main question
I have seen a pretty positive response for the AA tune and being that I have an AT I feel I could benefit from a new tune to help smooth out the transmission. But recently on some of the E90 forums I saw that the BPC tune might be a better option...
As a newbie I am looking for some elder statesmen advice. I am thinking about doing a stage 3 swap at some point but am worried a little about the reliability of swiping out the manifold as reliability was a big reason for choosing the 128i over the 135i... well that and price lol.
Any advice and opinions would be welcomed!
