Modded Corvette 2017 sloppy at launch

[se_sun1997]

Hi, I have a problem with my customer 2017 corvette, I made a tune on the dyno with some mods(overdrive crank pulley, aggressive cam, meth etc) and the tune seem normal no issue but finally I have a problem on the track, when I launch, at start the throttle cut and dont let the full power to the ground. The car was sloppy until the mid 2nd gear and after that it pull hard like normal mod supercharge vette, I try some modification in the driver demand table but was not very effective. I unlock only the ecm and I think the untuned tcm can make this issue but I want to have your advice on that!
I upload my tune and log file

Torque model needs A LOT of work just looking at the log.

I try to tweak the virtual torque table a lot but unfortunatly the problem was still there. In 1st gear the ecm wont let the throttle jump over 35-40% until 4500 rpm, then 60% and finally 84% at 5500. The other gear was 100% power

Peak torque needs to be lowered. accel threshold fixed. torque delta fixed. pratio fixed. That's just reglancing at the tune.
