Please don't correlate more boost = more HP. More boost does = more backpressure.

The best example in recent memory of this is when we did a headswap on a Vortech'ed 4.6 2V Mustang a few months back. The car was running ~9lbs with stock 97 heads, and after the swap to ported 99 heads it dropped to ~7lbs, due to the significantly better flow of the heads. Naturally, HP went up even with a reported loss of boost.
