    Your IAT's are way too high unless this is post blower.

    Part throttle knock appears to begin at MAP of 80-90 which is almost WOT for a N/A engine.

    I'd suggest running ~13 AFR around that point, perhaps back the timing off a little as well.

    Does it consistantly spike to 14* when you get back into the throttle after a pull? Or was this just a freak thing?

    It's called TCC lockup.

    Let off the gas and unlock the TC and get back into it.

    Try commanding less timing first. see how far that gets you.

    Are you using HPT or DHP to tune?

    who cares.

    op, the 5kr at wot would imply problems.. and they would translate to more at part throttle. Change your PE entry if you want to throw fuel at your problems, but it sounds like your car hates you.

    do not mask your kr with fuel. thats stupid and just hiding the real problem.

    re work the timing table.
