Ok, so still GTM canned tune mostly.
I had a rough idle problem with their tune even after doing the data logging and tune revisions (went through 20ish). Went to a local tuner who does VQ and it was the fuel/MAF settings that needed to be adjusted. GTM never adjusted this with the can tune, which is not a negative but on some cars it needs to be changed to allow for a smoother idle.
