AFC and boost question

ok so on my truck so far ive only done the free or cheap stuff to. exhaust, intake, fuel plate. and got boost and pyro guages.. been running 32 psi max. as far as i know there isnt a boost elbow and it is an hx-35 still. ive never done anything with the turbo itself.. but this weekend i finally got around to doing the afc modding.. took it off and ground down the afc barrel and swapped in a flat washer for the cupped washer. i put it all back together and set the pre boost screw in a little. just enough to wear i saw it push the foot forward. i plan to turn it back out but put it back on the truck and now im hitting 37 psi at WOT... is this normal or is something wrong with my wastegate/turbo. i bought the truck stock and its only gotten what ive put into it. so my question is why after modding the afc am i getting 5 extra psi of boost??? thanks in advance

Re: AFC and boost question

Your wastegate may be stuck. But to answer why it gained more boost its because you allowed for more rack travel with the afc

Find the end of the line going to the wastegate that's easiest to get to and use some compressed air (regulate it to about 40-50 PSI if possible). Blow into the line and see if the wastegate actuator moves.
