    Any reason to pull timing when no knock activity? 6 deg will make it mule when not in nitrous...

    Yes the car will be a dog when not spraying, I'd recommend 2 seperate tunes.

    These cars rarely show knock on nitrous unless something else is way off but reading the plugs will tell another story. They don't need or like very much timing on spray. I would also run ngk 6510 plugs in it.

    I will do that other way. I will put additional resistor into iat sensor started via relay, it will lower timing.
    But first I need new throttle plate since fuel valve is stuck closed, that's the reason of lean conditions.

    Thanks for answer.
