    Default 2004 2500HD 6.0ltr towing tune ?'s

    My brother has a 2004 Silverado 4X4 2500 HD with a 6.0ltr and I think it has a 4L80E(not sure)...He wants me to build him a towing tune. Anyone got some pointers on what I should focus on. I'm going to be honest I've never tuned a truck for towing, should I data log with the 28ft Toy Hauler attached or?

    Thanks

    Yeah the HD's have 4L80E's usually. I'd data log with the trailer, if you want it to perform ideally with the trailer.

    Yeah thats what I was thinking, First thing I'm going to do is the AutoVE on the truck and then see how it goes... Hopefully I can help him with his extremely bad gas mileage and the transmission gear searching when he's towing his toyhauler...
