Help required please!! new to this, but am having major problem installing a manual boost controller on my RB25DET series2. Got FMIC and pod filter wanting to intalls a boost controller but each time car misfires "splutter like" @ 6psi + and gauge it bounces on 15psi plus. controller is on low setting and tried with 2 different boost incase was faulty but same thing. its driving me insane. any help or ideas would be much appreciated.
