[QUOTE="kjk427, post: 1345183, member: 24533"] I changed the value to zero all the way down to 148 ft/lbs and all the way across the table to the highest RPM. Because at idle your torque is somewhere around 120 or so. Theoretically you will never be at high RPM with that little amount of torque. I figured not changing the parameters in the higher RPM was confusing the the PCM. After I changed all three vanes and all the back pressure tables accordingly I have had no problem with the tune.
