Message I have seen a Z that would misfire and POP around only under boost and mostly at higher boost levels that turned out to be a couple of bad coil packs! the car would idle and drive great until the boost got over about 16 psi. (higher load on the coil packs) If everything else checks out you might try swapping the coil packs with a known good set. ;-)
