I dont know why....(WELL Marco had a reason)....but my truck with just my Mach 2's doesn't defuel. I even let Rjohnson drive it (While i drove his

) and he felt the same way......Marco said that the 01's and up dont defuel for over boosting......

BUT i can say, with an EZ (or Smarty) and my Mach 2's....my stock clutch slips....bad......

The day I had my truck dynoed, I ran it without the Smarty on it for a while. It would still hit 35 psi and stay there. Never felt like it defueled at all. It put down 300hp without the Smarty. I thought it would have surged to 35 psi, then come down to 20ish, and feel like it hit a wall. With the Smarty, it would go to around 38, and put down 376.

Tate - 76 HP from a Smarty on a dyno. Nice numbers!! Right combo seems to make a big difference. Some claim losing hp w/ Smartys (on the dyno). Mine seems to add hp also!

What Smarty setting did you use?
