It does seem a bit rich but the factory computer is on the safe side of things.
One thing for sure is changing fuel pumps should not require you to adjust the fuel pressure so there’s definitely an issue somewhere. Have you swapped injectors?

Generally the fwd cals do need fuel pressure adjustment to be spot on, also +20 injectors are more suited to a 3 bar setup or an engine with porting work done. I had run the stage 3 cal for an 1989 2.5 car before and also the MP cal, the car seemed to work much better with the MP cal but this was before I had a wide band or a adjustable fuel pressure regulator. I eventually stepped up to the FWD stage 5, 3bar and +40s and I did need to drop the base pressure a bit for the wot a/f to be good.
I found it best to check your wot pulls on a cold night so you don’t take too much fuel away.

Remember what I said about outside air temp, you will be leaner when the air is cool and dense. Just be aware of that when you make your adjustments, the factory ran them a bit rich for a reason.
