Im not sure if this is the right place to put this but i just got the hks evc 5 and for some reason,i can not adjust the boost. it was working then i put my stock bov back on and the max boost i can get is 15 psi. just kinda wondering if anyone has an idea of what to try next.im pretty much at a stand still. any help here would be nice and i would greatly appreciate it.thanks alot.
