N26 Weird Engine Sound

Hi All, I have a 2016 328i with the n26 and for the last month i have been hearing this weird noise that almost sounds like electric buzzing. Like a lamp post when its on makes that weird sound thats the best way i can describe it, the only things i have done is a muffler delete jb4 and a charge pipe if anyone can try to diagnose with this little information i would appreciate it

Title:

If the clatter is strong and decreases as it warms up, it is time to adjust the clearances (or check the hydraulic lifters, if any), and if it is frequent, barely audible and does not change, then you should not worry - it is the nozzles that work.

Mine makes a very faint sound upon throttle, almost like a faint chirping sound. I noticed it after getting all my add-ons installed and my tune (intercooler, charge pipe, CAI, catless DP).

My indy/tuner looked the car over pretty carefully and said it appears to simply be the injectors pulsing as the sound goes away off throttle. It's been kinda weird.
