03 6.0 6 speed auto good towing tow with exhaust brake
I'm sure this has been beat to death over the years but I'm looking for help on a good towing tune with exhaust brake. I pull a 32ft bumper pull camper and 26ft pontoon boat not at the same time lol. I tow up and down alot of hills going and coming from the lake and camp grounds. Truck has ARP studs, new heads, bullydog cold air intake and pretty much a straight exhaust on it. It's 4in with a resonator on it to knock down the drown on the freeway. Any help or files to compare would be greatly appreciated.
