So how about anyone else, how good/bad is your mileage. I'm running a 350 with sm420 behind it...tell me it's gonna a get better after a good tune up lol. My financial advisor (wife) "advised" me to get better mileage or we both are headed for scrap yard.....

Say it isn't so, Dave! If you absolutely have (per your wife) to get rid of the truck, find someone who will give it a good home!
