Without seeing a copy of the tune no one can really give you advice on what to change in the tune. When I used to own my shop (sold in 2009) I did ALOT of tuning for dealerships because I could adjust many things with EFI Live that you can't with a Tech II. Unless they have something new with the Tech II or something different than the dealerships tech II's I used (up till 2009) you can't really tune with one.
It's not new the Tech II can be used as a Pass-Through device like the FlashScan V1
But you need the right software on your PC. The dealerships don't have the tuning software
they are stuck getting cals from GM, Like an AutoCal customer.
If this guy was a GM engineer he probably kept a copy for himself.
