Default 2.7 ecoboost f150

Low oil pressure code on my 2021 ford f150 2.7. I swapped out the sensor, no luck. Ran a multimeter to the harness for the sensor. Measured in at 5v ( i think that is normal) went to harbor freight purchased a gauge plugged that into where the sensor goes. Idle at 40 psi but when i gave it gas to 3.5k rpms it shot up to 95psi Truck is in limp mode as of now. I tried to reset the pcm by disconnecting the battery, still nothing. Truck is gonna go into ford for a diagnostic just seeing if there is anything i can do before i take it in since they said wait time of 1/2 weeks just for them to see whats wrong with it. Truck has 65k miles i did the oil change as well in hopes something was wrong with the oil filter nothing came of that either. I should state i took my whole front end apart while waiting for my paint matched bumper to come in and threw raptor 37” ko2’s on. Truck was ok then it threw a bypass valve code. Left it parked then when i moved it up to swap my bumper on once it came in i got the oil pressure light.
