    Boost readings question

    I have a 13 wrx and recently put in a defi gauge
    I been doing wot in 2 and 3 gear the boost gauge spikes at around 15 but then drop to around 11 /12 at wot
    I also notice that when I'm driving slow *barely touching the throttle * the boost is reading is at -25
    The idle is at -22
    Is this all normal or should I be worried?

    Do you mean dropping to 11/12 near redline? It is supposed to taper off as it approaches redline.

    When I go wot it shoots up to 15 and quickly goes back down to 11/12 I don't think it's close at redoing but ill check it when I go drive tomorrow

    That is not boost. That is engine Vacuum (mmHg). Gauges don't help much if you don't know how to use/read them.
