Boosted Boss 302 HP/TQ

So i just installed a vortech v3 with a 3.6 pulley, ID1050x's, NGK plugs, lethal performance boost-a-pump, and OPG/CS. Needless to say I'm disappointed with the dyno results. Only made 612 hp. My tuner said the knock sensors were going off pretty bad above 5500 rpm, but he believes it is false knock from the blower piping/long tubes or i got a bad batch of 93. Stated without the knock he assumes it would've made another 30-35 hp. Even if I weren't experiencing false knock, I was sure a boss on this set up would be close to 700whp? Am I just misinformed here? The transport truck gets here with my car on Friday, I'll try to find out that evening if poor fuel was causing my knocking or if its metal on metal contact.
