You should be trapping MUCH higher IMHO.
I have the same gears, same power level and i’ve trapped as high as 121 before. I run stock torque arm, stock shocks, stock rear springs with DMS lowering springs in the front, heavy ass boyd wheels up front with stock 16’s wrapped in MT ET Radials and I pull mid 1.6x sixties and i’m deep into the 11’s with consistent traps around 118-120.

EDIT: I also shift much higher, around 6900 IIRC though i’ll have to check my tune since I tweaked them a little since I started getting more slip and tagged the limiter a few times. My trans is on it’s way out but I don’t race enough to see spending the $ on it.
