Ah, so it essentially reuses the unburned gas in the exhaust? that's pretty cool.
Its not really that it reuses the unburned fuel (which I'm sure it does). EGR systems are put in place to reduce NOx, which is only produced when the combustion temperatures rise above about 2500 degrees. Be introducing exhaust back into the intake, it helps to slow the combustion process, thus lower the combustion temperature. Since I have my EGR vacuum stuff mounted inside the cab, I can tell you that as soon as the car warms up, that thing is on almost 90% of the time (clicks like mad). I would bet that have the JDM version will yield greater mileage, but I hope you have the JDM ecu as well!
