    1. Block off the EGR ("Free Mod")

    2. Remove the Air Pump (don't forget to delete it from the computer so it doesn't throw a code)

    The second set of bungs are supposed to be 'after' the cats.
    Search LS1Tech for a AIR/EGR removal thread. There was a really nice detailed explanation on it a few months ago.

    The EGR is the front passenger side only. The AIR is the one found on both sides on the top of the exhuast manifolds.

    Diablo hand-held tuner possibly.
    Or go to a Dyno shop & have the codes tuned out.
