Started off with the provided Whipple tune. Worked great with minor adjustments for months. Swapped to larger throttle body and intake. Dialed VVE good, made large airmass adjustments to help with idle timing and have made some small adjustments to virtual torque. Still learning and understanding the torque and airmass stuff. MAF has not been calibrated yet and still running speed density. I believe the MAF is my last step once I go back to closed loop.
Anyway, I am getting a large jump in axle torque when leaving from a stop. I seem to get this once I try to dial my Virtual Torque table in at idle to match the predicted ENG TQ command of 6. The closer I get to my idle timing around 10-15 and my engine torque to line up, I get this large TQ request leaving a stop and idle surge in park. I am clearly missing something here.
Other than this the truck has made amazing improvement and driveability is great. Cant seem to wrap my head around this one.
