Car keeps making shuttering/ rattling noises at around 4500-5000 RPM when stepping on the gas hard, it acts like it cuts out at above 4000 RPM before finally acting normal. is that a fuel/air problem? a head problem? or a safety measure that the car has? I don't know what to think about this noise

Can you make a video of the issue?

U.M.

my wife has a better phone than me, so I had her record while I drove. let me try to get the video she made uploaded

at 16 seconds listen carefully

i have to record another video, the wind wanted to mess up the recording

when it does the weird rattle/shutter sound, the boost is almost always above 24 PSI

This is purely a guess, but I'm wondering if you have one of the bad fuel pressure sensors that some EB owners got stuck with. I haven't had any issues with my car, but I decided to replace mine just in case. It only costs $20 and doesn't take 5 minutes to change it.

what were your symptoms?

I'm not getting any engine light or dtc's

how do you replace it ?

I had no symptoms, but others have had hesitation and loss of power. There are theories that bad sensors are related to the dreaded ecoboom.

Replacing it is simple: unplug the wire, unscrew the sensor, and replace it. Do it when the engine is cold to reduce fuel spill, and hold the fuel line with one wrench while you unscrew the sensor with another. Nothing to it.
