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.
