My GM4 very readily and willingly spins up 14+ PSI...Ive got the TM turned way down because when I installed my gauge, it was burying the 15psi gauge and holding it "wrapped". I dont see the other issues folks seems to have, like overheating, its never gotten over 195*...even towing, in late summer, in the deep south.

With a buddy tune, and an HX40 CKO, or ATT...this truck would flat out scoot and get 20mpg doing it...but its no slouch as it sits.
