2018 l83 6spd issues

[nandiotrevino18]

what's up guys? I recently tuned this 2018 l83 truck and It works good for having bolt ons, but it doesn't let me get the rpms farther than 5980 or 6k, it keeps it stalling, kind of like its overrevving, I tried 6100 or 6200 and it wont let it shift, it keeps it from shifting... any suggestions or what am I doing wrong? or what did I forget to remove? Ill post the log and the tune! Thanks and any opinion is great help!

I would try this first:
-Raise rpm limit in 6000rpm cells in 12063 Startup modifiers/cold engine
-Zero out 12067 Accel Thresh table under Acceleration based

It's the cold start table.

By any chance do you know how to activate the tune and make it downshift with the tow haul? Its different from the 14-16

Figure out what shift pattern is used for tow/haul and go from there, could probably be logged in scanner.
