Look at my sig for my fuel mods. If you played with the plate position, and had the right turbo, you should be just fine EGT-wise. If the 10 plate was in stock postion with a set of 370s, 191s and the HX-40 or equivelant, you would probably be sitting pretty good. My truck smokes pretty heavy if I lug it, but the AFC spring as loose as it can go without changing the spring. If I drive sanely and get the transmission to drop out of OD quick enough when needed, it doesn't smoke too awful bad.
As it is, I have the plate full forward, loose AFC, and the other mods, I see up to 45# boost and 1400* (1350* if over 40#).
I do tow some, and haven't had a problem with it so far. It ususally doesn't have to work hard enough to keep the EGTs up too high. Don't usually see te real high boost or EGTs towing, just goofing off empty, but is only there very breifly, since it gets up to speed so fast.
Sooooooooooooo, FWIW.
