The issue is reduced engine power at anything above like 50% throttle driving or sitting still key on not running. It revs fine not in gear and while rolling with clutch in. I?m thinking I wasn?t supposed to flash the whole file to it, just maybe cam tables and what else? To the original lap tune, but not sure and that?s why I?m here. Flashed original tune back just to check TB performance and of course I can?t run it in that tune but can?t replicate symptoms with other tune.
I get completely dead pedal and a P0606 pcm code when it trips. But everything seems fine back on 09 tune or 2.4 tune without a load. I?m about to push it off a cliff, any help or guidance would be greatly appreciated.
Corrupt repository tune? Can?t find any others from 08 ss cobalt manual to try though.
