4-5 % grade-26psi-1200F.....

Ya buddy, these tow like a mofo.

Towed the Harleys down to Marco Island Fl from Michigan for a weeks vacation (can't ride that far on a herniated disc). Loaded the hogs into my buddies 20ft enclosed trailer, dropped another fuel tank in the bed (60 gal), loaded all the other crap and rolled.

Hit a large hill on the north side of Knoxville on I-75, cruise on 84 mph, A/C cranking, Bob Seger blaring, 26psi on the needle, 1200 F showing and didn't even loose 1mph!

Man I love my truck.

Well we can agree on one thing, boost is cool!!! I'm more of an inline 4 kind of guy though . At least you're riding though!

...didn't even loose 1mph!

With only two hawgs in the trailer, and your mods, running 60-tow I wouldn't expect a downshift on a 4-5% grade, and the cruise control will maintain speed until it downshifts, then it will quickly regain the speed.

But any more weight and the EGT would probably sneak up over 1,250° on the 5% parts of the pass.

Your sig doesn't mention an exhaust upgrade. But surely you don't still have the stock muffler?

Yep. I'm blind in one eye and can't see out of the other.
