    02 WRX losing boost

    When I am accelerating(mainly in second) and reach about .1 according to my boost gauge, the engine loses boost for a split second until the boost drops a couple of pound and then builds back up and the it repeats until I shift. It feel like I'm hitting the rev limiter, only I am around 5K RPMs when this happens. Does anyone know what might be causing this?

    Are you using premium fuel? Are you saying it only does this in second? You really didn't give alot of detail. I mean if your expecting people over the internet to diagnose a car they will never see in person or drive in you might want to paint a bigger picture. You know like the problem just happened all of a sudden,has always happened,you have a CEL,you just put xxx part on,it does it in every gear at the same rpm.................
