Turbo Experts Question within The wastegate is supposed to maintain whatever boost level it is set to correct?
So if it's set to 5psi and then I throw a restriction like an IC into the mix the system should still crank out 5psi right? The wastegate should just dump less air to keep the boost level where it should be. Correct or no?
thanks!

i would say yes IF your pressure source to the wastegate is located at the intake.
if the boost signal is located anywhere before the new intercooler, the w/g will not be aware of the pressure drop after the intercooler and overall boost (if you measure it at the intake manifold) will drop off.

I talked with Dave just a min ago and he said on a conventional turbo that woul dbe the case but our wastegates are set up on the turbo so pressure changes after the IC might not make a difference on the settings. Does that sound right? Or maybe something to do with temperature changes and the diff. between where they are being measured?
yea they have it hooked straight to the turbo to avoid running more vac line all the way to the front of the car.. so the w/g never sees the boost drop after the intercooler.
