New tires. 2" shorter. Need your help.
#52
I set my truck to soley shift on RPM for WOT.... works much better than attempting to match speeds and rpm. Slightly shorter will not make it shift completely stupid.... I have swapped tires of various sizes and never had this problem, nor has anyone else I know.
That said considering you now have stock height tires again ( or close) and it's still not shifting correctly... I would go after it as a mechanical issue or another failure.
Reload either the stock trucks tune, or the original custom one. If it's not correct still, you have other problems.
And really, just get Justin to do the adjustment for you.... if it's still not shifting correctly after that the tune is not the trucks problem.

Well I put the stock size 20" tire on the rear and it made it slightly better but it still didn't shift at WOT and wasn't pefect.
I didn't measure the height but it is speced to be thesame height as my 17 tire.
Does anyone know what could possibly cause the issue as far as a sensor or other problem? I really think it is still the shorter tire because like I said the other tire was better but my guess is it was still a tiny bit shorter so it threw it off just slightly.
Thanks again.
