This weekends trip
Went from MA to PA this weekend. 300 miles each way. I was towing a 28ft enclosed. Combined weight right around 20k. Took I-91 to I-84 to I-81. Some fairly good hills, mainly in PA.
Ran the Spartan 300 on the way down. Other than a little surging pulling a few long hills, it was good. Tons of power. Temps all stayed in check. Truck never had to downshift even when I was slowed up to 60 on a few hills. Boost sat right around 42-45 up most hills.
Trip home I ran the Spartan 250. First time I have used the 250 since the update. Really nice tune. NO surging on hills at all. Smooth power. Shifts were smooth. Makes a perfect tow tune for me. boost was right around 35-38 up most hills. Both tunes seem to have a max of right about 1100 egt on long hills which is lower than I was expecting.
I would say towing is fine with the 300, but I would keep it in the 15-16k combined weight range. This is speaking as far as temps and what my short trip says. I would not start hauling through the mountains with it.
