Smoke20, cut off both cats and run a cheap glasspack or turbo muffler with a full length tailpipe. I have actually noticed increased power on my butt dyno by running full length tailpipes as opposed to dumped under the cab (don't laugh at me guys, it's true!)
Let us know what you think. How many converters do you have? Two?

6cylbill- i had the same thing happen when i still had my 4 popper ranger.
IMO, egr is the best emmisions device created (when they are working they do what they are supposed to, and can help mileage) and the pump is the worst (just...dumb)
get it tuned up and running properly, if you still want more do some mods, if that doesn't do it for you, just add boost...

Really? I wonder why this is. Maybe it has something to do with the scavenging.
