Project: 2003 BMW M3

Well, the SGT page made it fairly ambiguous as to what you were getting and I assumed it was a remote tune thing based on their wording. After talking to TTFS, it's actually an off the shelf tune specifically made for these headers. I can upgrade to a custom tune and get the data logger from them for $200, but I'm not really sure that its worth it since this is going to be my only power mod. I kind of doubt it will provide much of an improvement over the off the shelf tune, but every car does run a little differently.
