ok and he mentioned the smarty would add like 90hp on all settings its just the higher the setting is the faster it achieves it from a start in the rpm range i really only want it to bump my mileage dont need anymore power lol (something i never found myself saying when i owned a 7.3 powerstroke) :jump: so i'll just add the smarty and then forget injectors? im afraid to overdue it with the power as is with the smarty if i add it im afraid of hurting the trans also any idea how much power the smarty will add? also sounds like i'll be getting more of a mpg improvement with a tuner (smarty) vs like 75 hp injectors am i correct about that? and once trans is beefed up and i do injectors i'll have more of a mpg gain running injectors and chip? i appreciate all the help new to the cummins and autos always had stick trucks :tu:

The Smarty is only about 65HP, he's full of :edit: saying 90HP. He is correct on saying the levels determine how fast it gets to the 65HP though.

I believe would will benefit more from the Smarty over a set of injectors. The Smarty can also read and clear codes, add 3cyl high idle, adjust tire size, as well as add power.

I would do an Edge EZ and RV275s

Diesel dawg you don't think my tranny will hate me for that as in burn up?:scare2:K

Depends on its current condition, how you drive and how you use your truck. I've seen bone stock trucks burn up transmissions.

I drive very easy like a grandpa lol it was an old guys truck the only time I get into it a little is when I'm towing otherwise I'm after mpg not power lol
