No brake lights
I have a 2003 and have gotten work to it and I replaced the dash bulbs in the cluster and I got my car back from the shop and when I hit the brakes I have no brake lights but my reverse lights light up and my dash lights light up and turn signal lights are slow I have a hyper flash plugged in not sure if there’s a ground loose has anyone ran into this and my oil pressure gauge is maxed out almost the whole time even when cruising

Wow, that really hurt to read. Use some proper punctuation, it's not that difficult.
Did you plug in the hazard switch when you did the hyperflash harness? Does the 3rd (5th, center high mount stop light) turn on when you press the brakes?
Oil pressure pegged all the way up is a symptom of a failed oil sending unit. Plenty of threads on how to replace.

I'm 99% certain that the hazard switch was not plugged in when the hyperflash harness was installed. For the four round lights, the brake light signal goes through the hazard switch. There's also the possibility that it's the MFS switch, but that seems far less likely with the turn signals properly working.
What does the oil pressure read on the DIC? Does it read high with the engine off?

Change the oil pressure sensor - many of us have had the symptoms you describe, caused by that sensor failing.
90% cause of your brake light problem is the hazard switch - it was on mine and many others.
