Okay, so from 1000 to 5000 rpm's or so, my boost peaks at 7-8psi, but from 5000 to redline, the boost climbs to 10-11psi and stays there (until I shift, of course). I'm on a small Mitsu 16g in a '95 GSX with a cold-air intake, big-ass intercooler and no aftermarket engine management system whatsoever...
