    Slight KR at beginning of boost

    Just got the car together again and Im getting anywhere from .3-3.8deg of KR right around the beginning of boost. Seems to disappear once boost is at a flat line Running half c16 half 93. Was wondering if you guys could point me in the right direction.

    Thanks

    any chance the knock is a result of the drivetrain shifting from no load to a load? Asking because I'm not sure how you have everything held down. If you're on stock mounts, maybe try strapping the driver side of the motor down and see if it goes away. I've seen exhaust or any other part of the car hitting things bring in KR, cracked flexplates and a number of other items.
