After putting my stock air box with snorkel back on i keep throwing a P0172 code system to rich. so far ive cleaned my MAF, Switched out my Fuel Pressure regulator, and switched my injectors.... any suggestions to fix this problem???

Change the fuel filter and reset the battery by disconnecting the negative terminal. Maybe the ECU needs to relearn. And as fate plays some stupid tricks on us....maybe the front or rear 02 sensor does need to be replaced. You can also check for vacuum leaks at the throttle body or MAF as they can produce rich or lean codes.
