I had a 13 GT/CS on the dyno with a Roush Stage 3 SC package , OR-X and 75mm TB. Made great power,throttle stays fully open but after the dyno session I took it on a test drive for a driveability check. It had a slight surge at very low throttle range. I made some modifications to the driver demand table and torque tables. This fixed the issue but it will get the dreaded wrench light and around 3200-3500 rpm at part throttle. My question is what determines and drives this routine. Is there a max limit that drives this only that the actual current torque is compared to in order to monitor this routine? Attached is a copy of the tune before I made the changes that fixed the slight low throttle surge.2013 GT Roush SC 10LB_ORX_Magnaflow Comp.hpt
