Running Rich-rough idle with supercharger

theDreamer

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.

Damn. I don't have a local tuner really. Closest is six hours away. And you are right, it probably is still a canned tune... It is just weird that it all of a sudden went for **** in the past week as well as it seems like a boost issue, can hear it venting unless I really honk on it.
