I doubt the muffler will make any difference to your tune at all. Towing weights of 2000-4000 tells me a custom tow tune would be worthwhile, optimized for the 4000# load. The 2000# load could be towed with either the tow tune or a standard performance/economy tune.
I do think Bill can write tunes that can both save you on gas and still perform well. He did that for me. - Jack

One note on exhaust mods. A muffler will never require a new tune. It's what goes on before that and what you have changed. Please fill out your user info with hex/calibration code and serial number. Lars ![]()

The biggest difference in exhaust that would require tuning is for headers, crossovers (X and H pipes) and high-flow cats. These have a more dramatic effect on backpressure and subsequently can affect air fuel ratio.
