Is HPF M3's really reliable???
Hey guys, thinking about getting HPF stage 2.5 on my 2004 M3 with 26K miles. From what I have read, everyone is happy with the gains in power and performance. My question is regarding reliability. From what HPF states, there is no loss of reliability but is this really true? I live in california and if things go wrong, it would be hard to get the car back to oregan as I do not have a good mechanic that I would trust here. I really do not want to deal with check engine lights, programming issues, leaks, etc.
Also is there anybody in the SF area with a HPF M3?
