Elsewhere in this thread there was a comment about slipping of the clutch pack that was solved with a tune. What are the details on that? I will try to get more info from Cobb on the ghost upshift. Historically they are good with support.

I figured it wasn't worth the headache and sold it to a friend that has a gsr. Other than the idle issues, his car runs just fine.

I'm thoroughly convinced that if you run an ap then you must get a pro-tune. There's really no way around it and regardless of what cobb says about their ots maps and updates, the sst does not like their software! My special edition didn't like it, my co-workers 12 mr didn't, the person i purchased it from had issues with his 13 mr. Take it from me, ditch it and get yourself a tactrix table and use one of the free base maps provided here or on evox. You'll be soooooo happy that you did.
