Thats some great HP for only running the 6psi pulley and with the level of mods you have. The only thing that looks bad is the A/F ratio. You're running 14:1 up to 4500 rpm's. Thats WAY too lean for a SC'd car, you'll eventually fry a piston. You should really be at or below 12.5:1 all across the RPM band. You'll probably drop down closer to 300rwhp when you adjust the A/F but the motor will live a happy life. Also don't install a 3.4" pulley before you adj the A/F or your motor will probably puke the 1st time you go floor it. Here is the link to my recent dyno. http://www.corral.net/forums/showthread.php?s=&threadid=391737&highlight=d97gt
No it is not tuned. Just the Ford processor that came with the install kit. The program is from Ford direct. I do think the air/fuel seems a little eractic. Should I go for a custom tune or a chip to get it in the 12.5 range?
