Hey guys, I just got my truck tuned by Sutton Ford. I pulled 427 rwhp, 499.7 torque and have a air/ fuel ratio of 12.0. Just thought I would post and let you guys know.
Those are good #'s. Your a/f is a little too lean, a couple of tenths richer should keep you safe with the boost you are running. You just missed the 400/500. What timing are you running?
