Quote: Dyno'd with manifolds and switched to 2" TTI's becasue of heat issues.
I agree, I need seat time, practice with burn outs and launches
if you switched to TTI's after the dyno session, i would definitely shift the car around 5800-6000 and i bet you see a slight pickup of about 5 hundredths.to probably a .1 i did with almost the same combo. also change out that converter to at least a 4000-4500 stall.
Change stall even with with max torque at 2900 (650 ft lbs)
