38r mpg?

I have a TS chipped, exhaust, intake, leveled, 02 short bed 7.3 and was wanting to upgrade my injectors to stage 1 singles, and was wondering if a 38r would benefit the mileage and injectors or decrease my mileage

It all depends on how you drive. If you want MPG look to aerodynamics and/or gears.

In a very very basic way..... it takes x amount of HP to over come the drag and push the truck down the road. It then takes y amount of fuel to make that power. So lower the required HP to move the load and you will use less fuel.

The slower you go the less HP is required to move the load. the less drag on the truck the less HP it takes to move the load

Just a basic 01 F350 CCLB SRW -Good from a far but far from good

Along with what Tubular031 said, anytime you add more performance parts - there's always a trade off to reliabity, performance and MPG.
Don't get me wrong - Stage 1's and a 38r are probably not going to compromize your engine - but it will also be the tunes and your right foot that will ultimately determine how good or bad your MPG will be.

You will never recover the cost of the upgrades with the savings in fuel. Milage
difference will be minimal at best. Upgrade because you want to and expect no
savings from them.
