Does anyone know what kind of hp gains the pressure only tune in the X2 gets when stacked with a smarty?

I've been told they stack really nice but has anyone hit the rollers or is it the seat of the pants dyno.

 

I went from 439/921 to 492/1077 w/ the X2 added to my Smarty 4.4 back when I had stock sticks and less mods.

 

tcr do you remember what levels you were running on the smarty and X2?

Just so I have a reference point.

 

Never dynoed, but my butt-o-meter tells me tcr's #'s are right on. I don't know if this will help since I have an 04.5, but here are my normal settings. Smarty #7, RP2, TM2, TQ 3, Wastegate off, and the Quad on 2 with the fuel only tune. Anything over #2 and my rail pressure easily gets into the 27K's without a blink at WOT. Setting #2 will get it up to the 25's. This combo also gives me almost 22MPG on the highway. EGT's at WOT are just a tad over 1400.

 

Smarty Level 7 Quad X2 pressure only #3, or #4 ran the best for me. I really wish I would have dynoed the 4.2/X2 stack, it would be over 500 easily IMO.
