The CEL just came on when i posted this thread and i didnt know the tune was at fault (really, i still dont). I have had 2 track daus on this tune and probably 1000 miles of normal driving with no cel.
Edit: im bypassing the aem module as instructed by the tuner.

I wouldn't assume it was done being tuned until he tuner says it was. Your maf and ignition table needs some tweaking. Your fuel trims are swinging at times and can be triggering that cel. And the knock feedback could be caused by unfinished maf calibration or too aggressive ignition timing. Your power is being reduced currently from the global ignition pullback due to knock being seen at the 2800-3600 range.
It is not uncommon for 5-10 revisions to be required to dial in a tune.
