GMT 900 - TPS % Question

Just got my HPTuners and started some basic logging, and thought my TPS %'s looked out of whack. When I'm WOT, it never shows more than 83%, and on the low side, never below 18%. It's a 08 5.3 100% stock with a radix 112hh.

maybe your best bet is to start logging and smoothing out your fuel trims. start there. get everything in line except WOT first.
Im sure someone with more expierence will post up!

try this. the reason for the 18% could be because on DBW throttle bodies they never close fully at any time.
