I must not be understanding what you are doing. Why would you modify PE? Generally, if you are driving for MPG, you aren't into the throttle enough for PE to kick in.

If you are running super lean, and need a throttle position that pushes into the PE range... you can just raise the minimum throttle level for PE.
