    Load increase after Don Lasota's recommended changes, VCT maybe?

    So I made changes based on the recommendations from the coyote cookbook and my load went from 1.67 to 1.97 at 6800rpm.
    I'm wondering if my previous tune was bleeding off boost more or if something else could cause a higher load. I didn't make any changes to injectors or MAF values.
    Only thing I could think of would be the VCT changes.

    You changed cylair didn't you? With ONLY that changed my load went from 1.18 to 1.67, on a na coyote. My settings are based off the na cobra jet as I have that intake manifold and mono blade throttle body. Those settings are 1.3/.95.

    The Cylair WOT Multiplier is at 1.99 and the Cylair Max Multiplier is at 1.97.
    I have those same numbers in all my previous tunes.

    What about Speed Density->General->Airflow->Max Load? That was set at 1 and now it's set at 2.

    I think it's the VCT settings.

    Did you make any changes to your Torque/Inverse Tables?

    Did you guys ever make sense of the changes in load?

    Lasota makes a bunch of suggested changes without really discussing the ramifications of them. Some that I have looked at more closely are pretty questionable.
