A customer of mine has a 2012 LS3 swap in his 66 Chevy Truck. I noticed the throttle position is at ~20% when not pressing the gas and ~86% when full throttle.Is there a way I can re-calibrate with software? I am assuming that it doesn't start on the first crank due to this. It is a Stock motor and trans. with headers. By the bay I tool apart the pedal and didn't see anything obvious as far as calibration. Thank you in advance.
