You got me going in the right direction, but I guess my basic question is, how will I know how much boost I am running, still a little confused? Got the premise down of starting off with the boost controller closed and slowly open until happy, but when I get to that "happy place", how will I know what the boost amount is? Do I need some type of boost gauge? VictorSmalls, you state you are running 15psi, so my basic question is how do you know you are running 15psi, what tells you this? Do I need a scanner? Because the boost controller is a mechanical device I'm assuming the PCM really has no control over boost amount? Appreciate the help, just new to the forced induction game, don't want to over boost and blow up the car. I hope I'm asking this correctly?
