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.
