I have the PPE Standard with 5 levels. Levels 1, 2, and 3 are the same as the economy. I usually keep it on 2 or 3, and I really like them. 90 and 120 hp respectively. Level 5 is the WOW factor, but 2 and 3 are pretty nice, and less chance of killing the tranny.
You can't get on line updagtes with the economy verison.
Thanks for the replys, i am looking for a little extra power and economy of course. I tow 6000lbs daily so anything to help. I had a edge ez but i didn't like the way the tranny shifted, and i got about 1-1.5 better on fuel.
