Supercharged C7 with a forged short block. Car runs amazing and feels very strong. Made over 700 on the dyno but when shifting at wot the car stops pulling. First thing I check is the throttle to see if the ecm is closing it. No, it shows a clean full throttle pull with no dips. The timing dips but that is pretty normal during a wot shift. Car has been doing this since we installed the supercharger. I tried tuning the trans too thinking it might have been torque management through the trans. Same issue. I ran it with the traction control off too. It makes the drive a little hairy because power comes back in after the weight transfers back to neutral which causes the tires to spin again. Any idea? Is it the torque tables? Trans issue? Torque management? I know I'm missing something simple.
