    Kinda bumping this for whomever needs this
    But
    From research and this post alone its greatly helped improve my cars idle quality, lower IPW and overall running and my MAP reading at idle are much more acceptable (tho this could be me bumping my idle rpm up slightly).

    I have yet to take it for a drive to see if my exact symptoms of this post have went away but i am hopeful. And i think will be sucessful. I will report back.

    I know i keep bumping this post but id like to keep people in the loop who may experience this one day.

    Took the car out today and absolutely no more symptoms as the OP stated.

    If your lt1/sbc 24x swapped with lots of overlap i highly recommend looking into injection timing.

    I'm definitely going to look into this as my 24x can use some more drivability with the 235/243 .600/.613 109+4
