    Throttle position way higher than pedal. Full throttle at 60 percent!

    2003 Silverado SS with a silver blade corvette TB and a Xlink interface. The throttle position is way higher than the pedal. 99.6 percent throttle with only 60 percent pedal. There is no model number on the Xlink so I cant check if its the right one for a silver blade. Any ideas?

    Nevermind, guess its normal. A stock 5.3 Silverado does the same thing

    I did a DBW swap, and I have the same issue, the pedal, TAC module, and harness are all out of the same 03 Tahoe. I shortened the pedal so it would fit better. This causes 1st gear to be VERY jumpy. Pedal travel at about 60% is 100% open on the TB. Can this be changed? Travel be increased? Would a different pedal give me a bit better throttle feel?
