    Boost ??

    When I was cleaning my WRX yesterday I accidently unlocked the MBC and it got turned like prob 20 (guess) clicks...I turned it back around 20 clicks and locked it down however my the car is not hitting boost levels as it was before Im around 6 PSI off...IS there any simple way to go about gettting it back to where it was? Its an 02 WRX Built 2.5 Hybrid motor, GT32 Turbo, Alcohol Injection yada yada....Tuned by Romraider...


    Thanks in advance for anyones time and words...

    maybe it's too simple... but what about turning up the boost on the MBC until you hit target boost?

    What type of MBC is it? Typically the manufacturer instructions will have the initial setup instructions including how far from which position (left or right) is an increase in boost.

    If you can't find that information, Sinister's method is really the only way. Turn it up one or two clicks at a time until you're reaching your desired targets agian.

    I was thinking about that and I know you adjust them in small increments however, I was also thinking about how this might affect the ECU in terms of well...the adjustment of fueling parameters and such, I am prob thinking into it to much... ..I started adjusting it a tad this morning and I think I turned it a click or two to many fore I got a little boost spike.....
    Thanks man..

    I'm quite the opposite... don't know much in the way of vehicle repair, but I'm fairly heavily knowledgeable in the aftermarket side of things... Maybe we need to open a shop together. We need to throw Ron in on a Dyno, and we'd have a trifecta of subaru knowledge.
