I guess I'll go to the gm dealer and run the injector cleaner. Any suggestions ?

I get close to +7-7.5 at full temps which is 84-90 degrees Celsius. I check them in P or N.
But I also checked at start up too and seems to have in spec rates when cold, Weird huh? But when it warms up it gets worse.

Oh ya just to mention. It's been acting up ever since I switch from gray bottle power service to white bottle power service. ???

So a buddy of mine had the same issue with his lly edge combo. We found that the edge was wrong. Plugged in my EFI live scan tool and the balance rate was fine. Throw that thing away, plug in a tech 2 or EFI live and recheck it. His number 2 was reading 8.2 on the edge and 1.8 with EFI live.
