Not my car anymore...... But I can add this, the DBR stage 3 kit is bigger turbos, fueling, and a tune. It's pretty well documented, especially in the B5 S4 crowd, Tony tunes for insane power, and builds them as well. His mustang dyno is a heartbreaker. I believe their are tons of videos with pulls on other cars, etc. I would bet my $ this is one of the fastest if not fastest, that is NOT a stripped down drag racer. My .02cents
