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

Oh ok so its should fain boost ok. No I do I go about finding out of.my Wastegate is stuck?? A buddy of mine said it could also.be the actuator on the wastegate also???. Could it be? If so how do I test these??
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.
