if you have a pfc then you dont need the profec, the pfc can control the boost really well

Wouldn't the Profec-B be better because it dosen't use the stock solenoid? Dosen't it give better response also?

so does anyone know about running 12lbs of boost with stock exhaust? and if i do decide to sell it i'll PM you Fd3BOOST.
No, you cannot run over 10 psi with the stock ecu.



I would trust the Profec B over the stock solenoids, including when they are controlled by the PFC. It's also much easier to switch between two boost settings (or off for 7 psi) with the Profec.
