So just need some input or advice here. On my 03 my Smarty Jr just isn't performing like it did on my 05 or my 06 . I know the others were the 325 motors but thus one is a 305 and it just lately has been seeming to lack that extra get up and go. So I'm wondering if for the 03 if maybe the edge juice,ppe, or even the quad adrenaline with pulse might be a better option.my mileage is OK but not great getting 18 highway and around 11.5 pulling 10-15k.I use this truck for my daily driver and pull everyday so what yalls experience advice etc.... I was maybe thinking going with a fass pump and maybe wake the truck up aa bit to but not sure if this Jr is the right option thanks in advance

 

Anybody? Anyone at all have some advice or experience with the other programmers on an 03 and what have been ur experience,mileage pros cons just looking for some input thanks
