I can't imagine this would make any noticeable difference unless you're highly modified. I'd really like to see some dyno sheets with tuned with EGR vs. tuned w/o EGR on a mildly modified car. Hell, even on a fully built car I'd like to see it. I would think that advancing the ignition timing to compensate for the change in combustion temperatures would negate the need for deleting the EGR system. But that's just my reasoning. Anyone else?
The EGR is never open when your WOT, so it makes 0 difference on the dyno. The only reason I have mine capped on the exhaust side and open to fresh air on the intake side, is so I dont suck nasty exhaust gas back into my clean intake manifold. and it makes the exhaust manifold and intake manifold easier to remove.
As far as the resistor, that wont work, it would trick the ECU into thinking the EGR is operational, sure. But the ECU looks for a pressure differential in the IM when it opens and closes the EGR, hence the MAP sensor plumbed into the passenger side of the intake manifold. There is no way to delete the EGR with the stock ECU, and not get a CEL.
