Shift Points
I have 2018 Chevy Silverado that I had DOD/AFM delete, and I noticed my transmission is lagging in 1 and 2 doing acceleration and hard down shifting when stopping doing towing. If I send you a sata.log from the I3 would you be able to fix it?
Re: Shift Points
If you have the 8 speed tranny, then nothing can be done for the tranny at all.. can not do anything about the shifting... the 8 speed tranny is not tunable, so only the engine can be tuned.
If you have the 6 speed tranny, then you can get a custom tune done for it, as long as you have the inTune i3 8246 platinum version tool... The regular inTune i3 8200 version can not do custom tuning..
I can get you hooked up with a custom tune...
You can email me for info directly at: diablo DOT help AT gmail DOT com

Re: Shift Points
I’d start by checking the transmission fluid level/condition and whether any TCM codes are stored. Since the issue started after the DOD/AFM delete, the tune may also need some transmission adjustments, especially for 1-2 shifts and towing.granny 1 Posting the i3 sata.log along with your current tune details should give someone enough information to take a closer look.
