The secret to DWL is keeping MAP within the smallest practical range.
Result is that I gained a full 10% MPG while driving at exactly the same average speed.

What throttle position do you use on the hills now? What is it on the flats? Did you change any other driving behaviors at the same time? WOT is usually enrichened to get maximum power.
