SP2P 2bbl worth the effort?

I think EGR got a bad rap because people didn't understand it, all that well.
I wouldn't retrofit it to my engine unless forced to, but I have had good success tuning with/around it. It's a Part-Throttle device and when correctly working, you should never know it's there, under load or at WOT.
Anybody running a long-period cam already has some to a lotta EGR at rpms up to 2000 rpm or perhaps a lil higher. Chrysler exploited this in the early years, and so were one of the last car-companies to adopt EGR hardware.
