" If we don't go by deltas what can we go by?
I don't know about brens dyno numbers but I can tell you I'm a believer in his protune. I've had procede, jb4, cobb ots, and giac flash and my car has never felt like this. After brens pro tune, everything about the car flat out rips. Throttle response is perfect, no skipping or surging of boost/power. I'm very happy I went to him for a protune. I'm going back to him in a couple months for a e85 tune. "
