Welcome to the garage
7-8 mpg isn't going to happen, or not that I've seen. I would suggest an Edge EZ which only advances timing and doesn't add fuel, and a set of injectors, either Mach 1's or Rv 275's. The RV's are nice, cheap reliable, and won't destroy your trans, especially combine with only and edge EZ. The advanced timing of the box is what increases milage on performance boxes, and it also increases power a little bit, about 60-65hp maybe. With the injectors, a better spray pattern, and better atomization helps with milage.
I wouldn't expect any more than maybe a 2mpg gain though, just to keep your hopes from being too high. Also, with the amount its going to cost you, you could be a decent amount of fuel.
At $4.50 a 2mpg increase would save you .05 per mile. It would take approximately 16000 miles for these mods to pay for themselves. Don't buy them for the milage, buy them for the performance and view the milage as an added bonus.
If you are looking to mod your truck, then this is a good place to start. If you're just looking to save some money, well, you'll save more not buying the stuff. Thats all. Hope this helped and didn't just shoot down your plans.
