Just got back from ProDyno in Fort Mill, SC. Dan put the magic touch on my car, it made 543whp/536rwtq SAE. This is with just an intake, SCT 2400, SBTB and ported plenum and Stage 4 Steig blower, Bassani midlengths and offroad X, and a catback. 4lb lower, 2.93 upper max boost was 15.8 pounds. The driveability is much improved as well. Gotta recommend these guys up at Pro Dyno, it was worth the three hour drive.
