I'm no help but, have you checked out the HP Tuners forum? I've only read in the LS sections, but it's pretty good.Has anyone managed to disable the TCM down-shifting when you completely floor it in auto-stick mode? It drives me crazy. I've heard rumors that an HPTuners might be able to do this, but I'd rather not buy one just to find out.
Old thread I know, but can I ask how you did this?I can report back that indeed HPTuners allows you to do this.

You can (mostly) do this in HPTuners. Below 2000RPM I've not gotten it to work, it still downshifts. That's sort of nice though as when you're that low you probably do want it.old post ok , but i have Hptuner for TCM tuning , and no ........they can't disable , probably i'm able to do with WinOls and I try tomorrow
