At the track we discovered a sticking secondary air-valve door on the Q-jet that delayed the opening of the secondaries. With a little minor surgery, we repaired the problem. The nearby screw (arrow 1) deforms the soft metal and catches the air-valve door. You can also see the secondary metering rod hanger in this photo (arrow 2) retained by a Torx head screw.
