    Gfb manual boost controller

    Hi guys,

    Santa has been good to me this year bringing me a gfb MBC and a prosport boost gauge , but just have one question , it seems to be at peak at about 13-14psi, what is a safe gain that i could get to ? I was thinking 15-16psi ?
    Bear in mind it is a standard 2004 WRX that is used as a daily driver.

    Thanks in advance.

    To be honest is not something I'd be doing or messing at . Mbc are a sure way to make an engine go bang just my opinion

    Joe is right if you wanted to get power up in car might be best get it mapped upgrade few bits in engine instead of winding it to the top plenty of lads with wrx have got good results from safe mods

    Yup sorry to say as above,

    id leave it as is too.

    Invest in proper map session Mapper can increase boost to safe level while listening for knock/Det
