i assure you thats the only post i have here or anywhere else that has said anything negative about your tune, seeing as i dont know anything about tuning i was going off of what was said by the guy that looked over my tune, he said that it was running super lean and suggested that i not go into boost at all until the issue is figured out, the piston was looked over by a master tech at the local gm dealer said the most likely was related to a lean condition then i went to the tuner and heard what he said it was easy to assume, but at the same time i said i should have gotten the tune adjusted to my car the issue would have been found, its just as much my fault as anything else!
in the end i about made my money back parting out the old motor and my new motor and s/c has only 6k total miles so its hard to be even remotely upset lol!! also i would get your tune again just make sure it sits well with the car!
