[NO SLO PK]

There is no timing retard. My final run was at 11 degrees initial.

If I'm blowing black smoke, maybe the ignition could use attention. I have Motorsport plug wires, which probably aren't the greatest. Plugs are NGK. The 6AL and PS-91 coil are new. Cap and rotor are fairly new.

Do you have any experience with the Motorsport wires?

As far as fuel pressure goes, the regulator is set to about 36 psi under zero vacuum. I'm not certain what the FMU goes to...I'd like to back off on the FMU a little, but when I do, it detonates.

This is why I think it might be ignition. What are your thoughts?
