I ran 14 psi at the track yesterday and was detonating at the top of 3rd. My AFC values were all set to 0. My 02 voltage when I heard the first pop was .87v. I still ran a 13.8 @ 97mph on a 1.93 60'. I must have detonated and let off the gas right before the finish line, because a run I made on the stock turbo, I hit 14.1 @ 99mph. That was the only pass I made all night. I'm not going to run again until I get the car tuned professionally with larger injectors.
