Thumbs up Best MODS for LBZ !?

I am wanting to get some input on the best MODs for my LBZ. Truck is basically stock with the exception of 285 tires, donaldson blue power core air filter, and a Wix fuel and oil filter. What is going to give me the best fuel milage while still managing to haul the mail when needed? Best bang for buck?
And as far as fuel mileage...what should i realistically expect with the MOds?

Pretty much stock for now

The mods in my signature would be a good place to start. I'm running around 17mpg combination. You're also gonna get told to drop the emmisions and get a bigger exhaust.

For the best mileage per $, take it easy on the skinny.

I suggest starting with a free flowing exhaust and then adding tuning. We have great results with the Autocal with ATP tuning. Then it depends on your intentions with the truck.

Efi live autocal
Pcv reroute
Egr blocker or delete
Air dog will offer better fuel filtration also.
The stock air filter system is fine until 500 h.p Iirc but if you do want to put one on, s and b is nice.
Get rid of the wix fuel and oil filter. They are junk imo.

I didn't care for the diamond eye. I thought it was a pain to install and the exit angle is poor. I would go with a flo pro if I had to do it again. Bout the same price.
