I had a similar problem with my truck, but it ended up being that i had some major boost leaks with my twins and the AFC was all out of wack.My intake manifold gasket ripped, two of my compound couplers were leaking and i had a cracked boost gauge line..i would get EGTs in the 1100 range unloaded, and hot weather just made it worse. Towing? Lol Forget about it...with 10k in tow i was babying it and it creeped to 1300 at a consistent 20psi..Since then i have readjusted my fuel (5x14s) and pulled the starwheel back a turn and a half, and set the preboost screw back 1/8th turn and i make a healthy 47-50psi with my twins and I see 800 degrees after being deep into 5th after 75-80mph..not too much smoke either. Timing was Setup at 16.5
