Default Question on TBSS TPS%

Got my hp tuners in yesterday and did some logging on my buddies 06 Trailblazer SS.. at WOT im only showing 83% TPS.. i looked at all the tables i thought corresponded to that and they all showed that it could go to 100% at some point... Is there something in the tune i can adjust or is this something to do with the actual throttle body??

I noticed the same when doing mine. I think it has something to do with the torque management at low-rpm

This is normal from everything I've seen.

You can go in and log ETC% which will show 100%. The TPS% is just an output voltage the computer commands to fully open the throttle blade. When you convert to the C6/GTO/Z06 throttle body then you will need a full 88% TPS to move the blade completely. The blade will actually only miss a few degrees of movement at the 83% TPS output. Even with the blade not opening completely at 83% TPS we found that my SSR with the upgraded throttle body was flowing more air.
