Quicker spoolup is my main goal.

I'm using an old Profec-B with the solenoid pressure sourced from the UIM. The "OUT" side of the EBC solenoid goes to the top of the WG, and the side of the WG is being sourced near the Compressor before the intercooler.

Previously, I had the side of the WG pressure source coming from the UIM and I would get boost creep consistently. Have not seen any creep since sourcing from the compressor.

Thanks

get rid of the pressure source from the intake manifold. run pressure from the compressor housing to the "in" on the profec and run the "out" to the side port on the wastegate and leave the other port open(could be the other way around for the the wastegate, i cant ever remember)that could be part of your problem, but damn, that is absolutely horrible for response. when i had my regular 35r on a stock port engine with the 1.06 housing i was seeing 18 psi by~3800. the 500r just has a differend comp wheel if im not mistaken. that just seems really odd, especially for a ported motor.

have you checked all your intercooler piping for leaks? intake gaskets?

:edit: just read the above post copied from the other forum. the sp has a different hotside, but is getting better response than the standard 500r according to sean. so you should be hitting 15psi under 4k no problem.
