It just seemed like the car was detonating above 11.0, but that is more then likley because of the timing. Hopefully my tuner (JDRacing) and I can get things figured out enough to make some decent numbers...i would be elated if i saw more than 285 at 18psi. I'd be happy with what you have right now, but getting the most power out of your setup is everyones goal.
keep us updated! Im going back on the dyno in a few days.

Just got back from the dyno and I'm still pretty stump...I made about the same as last time 286whp/223trq on 20psi...leand out AFR to around 11.5 ish...messed around with timing some more but was not able to gain any power...I'm thinking it could be a bad dizzy or other ignition related problems...weird thing is it pulls a lot better on the streets for some reason...same power as last time, but feels much better on the street.
