I should mention not to exceed 4.7v. Mine is at about 4.63v if I recall correctly.

I believe anything over 4.7 sets a code. The PCM in my car says 99% throttle position at 4.04 volts and 100% at 4.06 volts.The goal is to get the throttle blade as close to 90 degrees open as you can without hitting the 4.7 volt threshold. This is for air flow purposes, not changing when the PCM thinks your at WOT.

I would like to use NOS's TPS Progressive controller which requires a WOT voltage of 4.7 to 5 volts
