Im not running a boost controller, just the standard solenoid, however it is pretty common for SRs to run at 10 PSi with a intercooler, exhaust and air filter. Ah on Srs im pretty sure the actuator signal comes off the intercooler piping on the "cool" side just after the intercooler.
Im reading 10 psi off the vacuum hose going to the fuel pressure regulator on my boost/vacuum gauge.
Cheers!!
