I lied! Problem is solved TEMPORARILY (but completely). I will post details after further thorough testing. So far, the throttle DOES NOT CLOSE at all on a WOT run from 0-78 MPH. It pulls hard the entire time, including top end which is new. Intake temps are normal. Boost is 25 PSI. There is no significant knock. Mixture is pig rich.In was mostly in the tune. PM me if you must know sooner, no one cares about this anyway.
P.S. – Neener neener neeeeeener!
