What boost did your gauge register just prior to knock? There is a overboost protection switch that will trip the fuel pump(s) relay(s) once boost goes past 1.1 bar (or so). If switch is bypassed and wastegate hose is cracked/removed the turbo will overboost and engine will probably ping.
Thank you for your time,
