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.
