Predator boost #'s

Those who run the diablosport predator what kind of boost #'s are you getting on WOT?? On heavy WOT I can get 25lbs once I get into a big gear that lets me load the motor down enough to let it pull. Just curious on what everyone else was pulling with that tuner.

I just posted this picture in a different thread as well.
I was coming back from vacation and climbing out of the Columbia river gorge with the CC on, the wastegate connected and in high gear going 65 mph up a long gentle grade. Maybe 2-3%.
Diablo Predator Tow/Haul tune loaded.

I might have a small leak, but I guess I'm not that far off though either. Thanks.

Diablosport predator here. In the 100 HP setting I can get it to hit 25 to 27 psi. Loaded with a trailer I can hit 32 psi if I am not careful.

Tecman you must have an air leak somewhere. That picture that I took was on the Tow/Haul mildest tune that Diablo has with the wastegate connected.
With a DP you should be able to peg your 30# boost guage.

I have my guage hooked up to my MAP sensor, could that read a different reading than having it taped in somwhere else?

I will go over all my hoses today checking for any leaks.

Got a boost pressure relief valve on the MAP hose?
That will effect the number.

I have a reg from ITP. Im tapped in between the manifold and the reg. Other than the AIH, where is the most accurate place to tap a boost line?

That one doesn't bleed pressure and where you have it is accurate.
