because it comes with the autocal...it isn't just for a tune, considering dyno tuners want $500 here, $650 with autocal and 3 retunes is a good deal...of course, that's my opinion and I have been debating my tune for well over 3 months!
Ask Blackbear how much his is. I believe it was $500, and then went up some. BBP is good, but Pat G knows the G8 cars REALLY well, as he owns one and modded it heavily and is well respected on many forums. The only other tuners I was going to consider is Rick Crawford, and his communication sucks and he is always backlogged, Futral motors in Louisiana, but they couldn't give me a solid answer. First I was told it had to be in person, then now they said they can do email tunes, but never got me a solid reply. The local two guys Sam Miller and James Karger are either a pain in the ass to reach, or prices tend to change frequently. I decided this was my bet route.
