you know when i first got the car mine did that too when i hit full boost in the higher rpms and my car was bone stock. it scared the shit out of me cause i just got the car and i was like whoa... beeping? my car would also jerk back and forth very quickly right before the beep so i made sure i didnt do it again whatever it was. then i decided i was going to find out what the beep was for and then my cars starter died and the dealer told me i needed a new engine. no lie. so i started ripping the engine apart to see if there was damage to the block cause the dealer told me it wasnt rebuildable and then i found out it was only the starter, when i put it back together... it never happened again. so it could def be knock i dont know for sure tho.

id still like to know what it is even tho it doesnt happen anymore
