My evo has always held 20psi till redline with the greddy profecb.....the first style.....and now after the install of my aem intake it starts droping psi after5krpm till redline...it drops about 2 psi.......and all my hoses are tight and stovk bov clamps too............is it possible the ecu is freaking out and dumping boost.....by the way my car isnt runing that strong anymore since the intake....would i be better off atleast putting the stock intake pipe with a open filter or just putting the stock box with a k&n drop in?
