let me know what i should do..thanks
 
damn thats pretty amazing to me that your runnin 21psi on 91 octane and are way rich........with the settings where you got them i dont see how your rich.....but lean it out until you can get .92 across for the entire rpm band....you should also try to get timing to aroung 18-20 degrees at top end......from 5400 to 5700 your timing goes from 7 to 4...you might have a little knock there......as long as you have .92 for your o2 voltage and your timing keeps advancing during the rpm band you should have a pretty decent tune..good luck......

I was thinking the same thing. I cant believe your running that rich at 21psi. I would tune the car at 15psi and not 21psi, so you have a less chance of breaking something.
