Not shifting in W.O.T. acceleration..
So I had some issues when I changed to bigger tires on the rear with T/C and stabilitrak. Only solution was to get bigger tires in the front. Now I am riding on 285/35/20 up front and 305/35/20 in the rear. Now when I am doing a pull it almost seems like it hits a wall at 7k rmps before it shifts for about 2-3 secs, then it shifts and goes hard again. Could this be due to the tire increase? I haven't tried changing anything on the tire size on HPtuner.
P.S. Normal driving, even fast acceleration shifts fine, just not in WOT.

Changing tire height is like changing rear gears to an extent.

Did you adjust just tire height using the gear/tire wizard in HPT... select adjust speedo and scale transmission?

Just looked into the tune my tuner sent, it does seems like he change the tire size to 28.4 for the 305/35/20 rear. Now I do not know if he scaled the transmission.
