Is the knock due to octane/detonation or mechanical. Add some octane and see if it goes away. If it does, lower your boost. Easy. If it doesnt, then find whats cuasing it. Downpipe, tranny, etc.
Without being able to record your knock, no way to tell when its happening, except with a co-pilot and patience.
