    Default external wastegate help please???

    hey all
    i put bigger turbo on my car and the internal gate ended up being to small over boosted.

    so my tuner said we will run 14psi in ur engine.

    i bought a 46mm wastegate with a 14.5psi spring does this mean my car will run at 14.5 psi on the boost gauge or does it mean this is when it will start to crack open at 14.5 . please help im new to external gates and how u ditermin boost levels thanks guys
