I'm tryin to tune the car using the PF, but under load it hesitates or misfires at about 7-9psi(usually around 3k rpm). Now when I log it shows AFR to be around 11.1-11.8 on anything less than 70% throttle. But anthing above 70% its in the 9's or 10's. The more throttle the richer it goes. But I have only been able to hit like 9psi before the misfire happens. So should I continue to lean it out and hope that takes care of it or should I be looking for other problems that may be causing the miss. The car idles and runs great if its not under load.
