Today I finally got to use my 25+5 trailer and load up some hay in SC.
My setup is stock fuel running an awesome Stainless Diesel S467.7 5 Blade, ARP 625s, Steed Speed, DRD, etc.
I loaded her down on the 30-hp tune, and the highest I hit on the toughest of grades was 1250 EGT.
I won't lie the one mountain pass from SC to the NC mountains had her screaming at probably 2750 RPMS fluttering 1250 EGT, but she made it perfectly, and that grade is brutal.
I am very impressed with DRD's tuning and my turbo setup pulling this weight.
If you are looking at a second-gen swap and tuning, this is where it's at.
