If I have a broken Map sensor and replace it but not clear the code, Is it still broken as if the map sensor wan't replaced?

I had a broken map sensor but I replaced it. I did not get the computer reset for the code that it was throwing because it couldn't move because of a broken tranny.
I have a fuel pressure regulator that is set at 42 psi. When I went to the dyno the map sensor was bad and so we set it at 32psi (was the best pressure setting so I didn't run lean.) Should I set it back at 32psi or should I leave.

 

Anyone?

 

Just unplug the pcm fuse for a few minutes, it will clear the code.

 

Will this clear things that Pcmforless or dyno tune did??

Where is the fuse for pcm?

What should I set the Psi At when I reset it?
thanks
