Doing some logging and tuning today on my 07 corvette and just noticed in the log that when wide open it never hits 100% throttle position. Is that how it is supposed to be? Here is my log. It shows it maxes out about 88%. Is this normal?

After some searching it seems I may not have the correct throttle position PID selected. Anybody know what PID I need?
ETCTP or similar I believe.

2008 TrailBlazer SS 3SS AWD Summit White - LS2 E67/T42, bolt ons, suspension, etc.
2002 Chevy TrailBlazer LT 4X4 Summit White - 4.2L I6 P10, lifted, wheels, etc.
I just went out and selected all those type of pids and turned the ignition on and it still maxed at 88% when pushed to the floor. I thought possibly it was the aftermarket throttle controller so I unhooked it and put it back to original and still the same thing
You may just have a bad TPS sensor or it may need to be calibrated if it's ever been replaced or removed for any reason.

88% is WOT. Take your air intake off and with key on engine off have someone hold it to the floor, it show 88% and the TB will be all the way open.
If you log TPS %, then you won't see a value over 88% (as it is calculated from the voltage).
Log:
GM.APP - for the position (%) of the APP (accelerator pedal)
GM.ETCTP - for the position (%) of the throttle body
Both of these PIDs range from 0% to 100%.
I tried to log those you have listed but it didn't do anything. Kinda strange.
