    EDIT: The idle timing is fine for E85. This is a good table.
    Thank you.

    On the plug reading, this is one of the best articles I've found. It's old and from a motorcycle angle, but great info: http://www.strappe.com/plugs.html

    Something on spark plug reading I found on another site, written by someone else.

    Guys, Thank you for all of the help.

    My table looks very similar to what 3 window posted just at a lower map scale.

    I went through a set of plugs and just slowly crept up on the timing above 100 KPA. I am not sure what my power level is now but it feels like it would be well above the Dyno sheet I posted earlier. Its on E85 now and 12 psi. It will blow through the converter and hit the rev limiter if I floor it instead of roll into it. It builds boost much faster now and runs much smoother. I would love to get this thing on a dyno and see what its doing now.

    Now I am looking at a 4L80E from Jakes and PTC converter.

    This is with a conservative 60' tune, leaving at 7 psi (no Boost Builder).
