Ok. Before you agree to any work come back on here and explain what they want to do and all your symptoms. Got some great Dealers out there and then the other ones. Some mechanics and some parts replacers. At least you'll know where you stand when you go back. Good luck

Jimbo, I don't know the early 2004 so I hope someone that does will jump in.There are a few differences between the 04 and the 06 like HPOP, dummy plugs no stand pipes. Your fuel mileage will settle back down. When I got my last flash it reset the mpg gauge and mine did the same thing. I got excited ;-) then it slowly settled back down.
