Well add me to another very satisfied smarty owner. Programed to #9 and I finally feel like I have the truck that i paid for. One question is even with my adjustable elbo all the way in I could only make 26 psi boost. Im guessin thats about right considering its my only go fast mod for the next 10 minutes. well thanks to marco and rip. Gota go put the hx-40 on now. will post how that one turns out too.
