New to tuning, have been reading a lot on here and watching youtube. I feel as I have the MAF tuned pretty good and have went on to speed density. The issue I am having is when failing the maf and codes p0103 is set to first fail the trans shifts very hard as if it has full line pressure. Have not seen a way around this. Is an 07 Yukon 5.3 truck norris cam longtubes catless y pipe MBRP cat back and an intake. e38PCM. any help would be appreciated.
Can't see what's in your tune file unless you post it.

There will be ones for Freeze adapts, max pressure, torque man inhibt, etc.. Set them all to disabled and that will take care of it.
