Well, after 1 aborted install attempt (wrong connector cable which Mike handled immediately, thanks again Mike), I now have my EPP working on my 2009 Ram 2500. I don't have access to a chassis dyno but I DO have a Dashhawk that can datalog performance runs. So, I took my truck to my favorite little-travelled road & did some 1/4 accelleration runs. With the EPP set to 0 on the dial (just like stock I guess), the Dashhawk reported a best of

[email protected]. I think that I might have lifted too soon on that run because it is very difficult to tell when the Dashhawk reaches the end of the run. I would guess that the MPH would have been slightly higher if I hadn't lifted. But the reduction in ET is considerable from "stock" to "extreme".
Almost a full second reduction in ET is HUGE....especially on a 7000 lb truck!!
I also noticed my highway mileage was almost 23 mpg as reported by the onboard trip computer. I don't know how accurate that puppy is but it was reading more MPG now than it did before the EPP install. I had the dial set at about 80% during the highway driving.
Tomorrow I'll be towing my 8000 lb travel trailer and I'll be able to get some more MPG data to compare to the "before" figures. I'll post my results when I get back.
By the way, my truck is stock except for a S&B cold air kit and the muffler has been replaced with a piece of 4" straight pipe. The CAT, DPF & the EGR are still as delivered from the factory.
