Trouble with these owner sites is bad information. I never liked the RPM detection for EGR functionality. It seemed like a reach.

Mr. Dalton nailed it. Manifold pressure monitoring - cool! I've read considerable (user) info looking into defeating EGR. None of it was correct. The tuner crowd buy programmable modules where they define ranges for EGR to turn on. Like when the engine reaches 300 degrees or when it hits 240 mph. Basically, a simple parameter (in outer space) allows you to blank them off and never trip a code.

Wish we had those. Blasting exhaust into the intake just sounds wrong.
