Max for stock turbo with stock tuning will be 20-25psi depending on the year truck, geographic location, and of its EGR deleted.

My truck would hit 28psi stock per the scanguageII. Pretty much the same tuned, but I don't stare down the SG2 when at WOT

Mine goes between -.4 to around 1 psi......Depending on what the turbo veins are doing and barometric pressure.
