New to this and learning to tune, my setup 07 suburban 5.3 lc9, e83 ecu, whippel, stage 3 tsp truck cam, full exhaust no cats, 4l80e swap and a bunch of other stuff, my question is when I recorded a scan my tps% only went to 83.3% at wot along with my throttle desired, I assume it should be able to go higher, what needs to be done to get my throttle to open up more? Thanks im advance
