Strong gas smell when starting

Just a note, but i decided to check and see what fuel trims were doing after everything was warmed up. Long terms were pegged at 0 for both banks while short terms were pegged at -25% and would go to 0% when the rpms dipped to 600 and climb back to -25% when rpms came back to 1100. I tried driving the car while the mafs were disconnected, it would not let me go past 2500rpm, but seemed smooth otherwise. I recorded a few minutes of data while the mafs were disconnected that I’ll upload here shortly and see if we can glean anything from that if necessary.
