have a 5.3 swap in a 68 nova 4L60E trans LS6 intake, 07 hummer computer,truck throttle body DBW, corvette pedal, corvette TAC, for some reason I can only get 70% throttle when floored my obd2 scanner shows only 70 tps so I took of the intake and looked at the butterfly had my buddy sit in the car and floor it and it's only opening about 70% I thought maybe it's a bad thottle body so I took the one of a friends truck (04 silverado) and put it on my car and same thing the pedal is not even close to hitting the floor. any body have any idea why this happening? I just finished the swap and man do I love it even with all the bugs it has

what pedal do you have? I think we need to trade stuff, as mine does the opposite. 70% throttle makes my butterfly wide open.

I have never heard of anyone using a truck throttle body with the C5 Corvette pedal and TAC. Maybe that's your issue?
