I've had intermediate problems with the TB closing at 2700 rpm and opening at 3200rpm ever since I put the Magnuson 2650 on. I'm doing my own tuning or at least trying to. A/F and Timing no problem but the torque is killing me.
I think it's the torque table for MAF and MAP but maybe I'm missing something.
I'm running an LT5 TB so maybe that's the problem. I'm at my wits end. Any help would be appreciated!
