Thinking about putting my truck back to stock, so should i keep my flux's since they have a better spray angle and such, or put stockers back in, also this will be used for daily stop and go towing (about 5k lbs)

 

Put my stockers in and Iwill bear the burden of those awful flux 2

 

My tow rig gets decent mileage when just running the flux 2's with the HTT 62/71/13ss but the egts can get hot in a hurry without any timing. Thats towing my 12k toy hauler though. Any little hill results in 1300*. Putting smarty in on level 1 with timing on 4 results in way lower egts but a concast amount of smoke on any hill, no matter how small. Even some cruising flat.

I like the truck with injectors only and it dynos at 375 with ONLY the injectors in it.

 

Id try running just the injectors first and see how your truck reacts mileage and performancewise. My 03 got 1 mpg better with Flux1s in it...

 

Don has milage injectors which add a couple MPG's and about 25hp, theres also Flux I's

 

So would a pressure box help with my mileage?

 

Yes, but be careful. Pressure will kill injectors. Right foot control is key.
