Gmc Sierra(4400lbs w/ driver), lq4 on 11psi

Heres the best comparisons I can come up with:
Footbrake: Stock 2200, PTC ~2500
Flash Stall: Stock 2000-2200, PTC 2600-2800
Converter Slippage: Stock 6.5-7%, PTC 7.3%
Shift Extensions seem real close

Lane said it should be a 3000 stall. Does this seem right? Will a hydroboost and 2 step raise my footbrake to a reasonable amount? Also, will more boost push this converter better? Heres the best videos I have at the moment.

Mild acceleration. This is about the only place I noticed much of a difference. It stayed "in the converter" on the shifts. I didnt feel as much of a bump when it shifted.

40 roll. Cant tell much of a difference here.

Give me some advice people! First turbo verter. Wanting to know if I should loosen it up or try to "grow" into it with braking mods/more boost.

 

Anyone have some input?

 

Needs to be looser on the bottom IMHO. Give lane a call. Him and Kenny are good people. They will help you out I'm sure!
