what does it take to remove the A.I.R pump and egr from a 88 tbi 454 without throwing codes
Short of burning a new chip. Try leaving the EGR solenoid hooked up. Sometimes that works, but may set when the O2 figures out what you did. As far as I know the air pump shouldn't set a check engine light.

when I wired my TBI 454 ( I used the painless harness, so this could be different but its worth a try), I wired the neutral safety switch so it would always think it was in park, I was told that in park the smog controls aren’t used so no codes thrown when disconnected.

Again this was for the painless kit so I don’t know if it would work in a stock situation.

if so that might be what you need to bypass.
