randy its opening 100%, there is two tables to read, on hptuners site there is Q&A about this allready.

 

but i have efi live and they don't help there

 

Im sure efilive probably has the new pid GM designated for logging purposes. In hptuners its ETC position %.

 

One thing I did notice in my stock tune (mine's DBW as well) is the pcm will only allow a max throttle position under certain circumstances, there's a table under trq mgmt that limits throttle pos. called ETC TPS Max

 

Check the Throttle system in the PIDs tab. Look for ETC Throttle 1 and 2 as well as any other PIDs that are available. Wouldn't hurt to log a bunch of them for a run to see which one best shows what your truck is seeing.

 

My GTO only shows 83.1% at WOT as well...I remember reading somewhere that it's the PID that does it. Let us know what you find out.

 

thanks and have not forgot about you with the pcm's

ok i will do
