would a boost controller solve this?
recently my pfc has given me problems controlling higher boost levels. I have two boost settings in the pfc... for 12 psi and 14 psi. I have zero problems with the 12 psi setting, as my boost is always consistent and stays at 12 (except at transition, of course). At the 14 psi setting, my boost will hit 14, dip down in the transition (sequential twins), go back to 14, and then at rpms above 5500 it oscillates back and forth between 14 and 12 psi... The strange thing is that I only started having this problem over the past few months.
Anyways it seems to me that this is a boost control issue, and that the solenoids cant keep control at 14 psi and they bring it down too much to compensate, then bring it back up, then overcompensate and bring it down... etc. Does this sound right? I don't know much about how the solenoids control the boost, but would an aftermarket boost controller (profec) solve this problem? I would really like for the car to hold 14 untill redline like it used too... it just felt so much stronger.
