Looks like you have hit the nail on the head, John.
How much for a bundled 4-5" exhaust system and the switchable Performance/Economy Tow tunes for my '05 LLY?

That would run approx $1200 off the cuff.

Do you expect better towing fuel mileage with the 'ECONOMY' setting over stock? I'd be happy to use my '05 LLY as a test mule towing 25' gooseneck trailer and 6-8K loads with the 'ECONOMY' setting. As long as the overall towing mileage was better - I'd buy that tune.
I may have asked this before, but is it possible to have the ECONOMY towing tune engaged only when TOW/HAUL is activated, and stock programming otherwise?

Brandon has been knocking down 11mpg with his LLY on the race tune. This is an improvement for him with this same load.
As for which tune is used when, we have a simple toggle switch that will take care of this.
