Yeah it is near impossible without efi live. From what i've seen about 450whp is the max for a solid, safe towing tune if you are pulling heavy with a 5.9. I imagine the 6.7 can be run a little higher but i wouldn't think 700whp would be safe especially on a single.
The truck was built for it. 700hp was pretty conservative for that truck. It was a work stock truck that we used to pull the 3.0's and outlaw trucks around and then unhook the trailer, swap the tires and wheels, adjust the track bars and pull the work stock/2.6 class with. Set on kill it was around 1100hp at the crank but unless we were close to home we never ran it that high in work stock. we would pull around the 900 hp range @ 75lbs which was up there for the mods but still conservative enough where we didn't torch the heads or rings. We always had drive shafts, ujoints, and suspension parts on hand in the trailer if and when things broke to get us home.
I could never justify driving two truck and trailer setups to run 3 trucks. We compromised and combined the tow vehicle into our work stock truck. The 3 years we ran like that we always finished top 3 for the season (winning two seasons) in work class and were middle of the pack in 2.6. 2.6 trucks are around 1400hp now-a-days so we couldn't compete as well. If we had a bad night and didnt get power to the ground we were fucked.
