I just completed my swap in my 97 hatch. It seems to be running really rich, I can smell it out of the exhaust and I checked my plugs and they show to be running rich. There was a lot of black smoke when i initally started it but it went away, but i can smell it. I am not throwing any codes. My fuel pressure guage is showing it at 40psi at idle with the hose connected. I checked all of my vacuum connections they are on there tight and secured. Should i just get a VAFC and get it tuned to run normal. Could it be because I am using an old O2 sensor?

Here is the info on my swap
LS/VTEC
AEBS intake mani
P73 ECU

B&M fuel regulator
