also, would it add more fuel to a d16a6, or dont even bother messing with it and just leave the pm6 in?

PM6 is designed for a 1.6 liter sohc motor.

PR4 is designed for a 1.8 liter dohc motor.

i intended to actually go b18a turbo, but i think im sticking with the d16a6, so i bought this ecu before i decided to stay SOHC...i wanted to make sure its a 5 spd though, like the owner said...

yes 90-93 integra ecu's are PR4 but remember that the 92-93 PR4's are OBD-1 and can't be used in 88-91 LS swaps unless you do some major rewireing!!! You need a 90-91 PR4 ecu...
