Evo III 16g Gate Pressure?

[TurboBlue]

I recently put a 255, fmic and evo 16g on my car, but since i still have the 450's, i got rid of the MBC and just T'd my BOV vacuum line to the wastegate. I was told this should produce about 12 psi...any one know if this is accurate, and if not, what sort of numbers are more realistic?

It might be more like 15psi on the Evo3, not really sure though. Why not just floor it and find out?

like 10-11psi

Why not just get in the car and find out?

mine is 12psi i am running just about the same setup but i have not put in my 255lph pump yet cause i hear it does not run well with out a fuel pressure regulator. i have a 3" lt1 with a MAFT ram chargers but even at 12psi i still hit fuel cut but i don't knock and i run on the rich side of things to redline with the data logger.

It's between 11-12 psi.. But it's actually suposed to be 11.1psi. I havnt hit fuel cut yet on my setup. Hope this helps.

well, turns out to be just about 10-11 psi, no fuel cut, and runs fine without an AFPR

i also get between 11 and 12 lbs of boost without a mbc. i am also still running stock exhaust (for now), had to replace my dead 14b.
