    Hello, I created a video demonstrating how I modified my EGR tube to no longer take up space inside of my intake manifold plenum mouth, which creates turbulence and hurts CFM.

    This mod is for the 4.0 v6's, unless other engines have a similar EGR tube

    I wish I did a before/after dyno pull, because my butt dyno says there's a power increase

    This seems like a good modification. Has anyone who has done this noticed an increase in power?

    This mod wil not add any power. Please prove me wrong and post dyno numbers before and after.

    i dont see how a 3/8in tube will cause engine to loose power, or obstruct flow. maybe a few CFM but not much. you get more obstruction from intake itself, etc etc
