I get a knocking noise around 2k Rpm you have to get really close to the engine bay to hear it but itís there and you hear it while driving but only on 1/4th throttle and letting off. Not sure what it could be?? Timing tensioner?? Rod Knock?? Should I get a retune?? And oh I started having a boost leak from oem tgv and oem Turbo Inlet not sure if thatís the cause had this noise for a while

Does the noise get louder the higher the RPM? Or does it stop after 2k? How many miles are on it?
