Well In short i'm looking for a pressure box. A friend of mine who has a bombed 07 with the smarty mp-8 shows no gain in hp from off, to 100% on. So I don't know if it will make a difference on my truck. I'm looking for highest horsepower box that will play well with the smarty. Beta 4.4 is great but it only made max 461 on the dyno, and standard smarty #9 and puck on 60 made 505. The Power Puck makes power but defuels because of overboost condition(48-49psi) and defuels so it is not dependable power. I know that there is the Quad box,Dr predator,and a F1 pessure box. I'm quite interested in the F1 box seeings how i'm getting flux 2's next month. I need suggestions. Anyone is welcome to give advice.

 

I have had a dr. performance 2021 pressure box and it was okay but I really like my X2 box which has lots of interchangeable tunes which each have 5pw levels to choose from. I am running the beta 4.4 smarty sw #9 with x2 pressure only stacker tune lvl 5 ran 13.309 and love the combo.

 

We found that standard smarty worked better on the dyno. We ran mp-8 at 50% and 4.4 and the rail went up to 28,000 but no extra power and the truck has supporting mods, cp-3 fass and don m's.

 

I can't say to much about that but im not looking for a dyno queen, just building a DRAG QUEEN. LOL

 

Standard software didnt pull near as hard as the beta 4.4 did and I never saw over 25kpsi with that stack.
