my car is starting to "feel normal" too. i would check for boost leaks. spray bottle is what i use. i had an injector ring that wasnt sealing right, once had a fuel rail bolt fall out. maybe its your gauge and your getting "used" to the additional bump.
i know around here, i can feel the difference in performance when its HOT out. boost pressure is the same. what is your vacuum at idle in -psi?
Also belt slip is possible**** whats your tensioner set up? belt size?
