If he's moving the actuator, it will absolutely affect part throttle knock.

Where are you seeing this knock? It could be possible to see a bit of knock right at the shift, which you should be able to tune around. It's also possible that the solenoid is bad and lowering your boost, which would change your knock levels, of course.
