You won't feel the difference immediately - long term effect. Best bet, set
it where you feel comfortable and have a local dealership set the Fuel Sync
to "6" +/-1 with the DRB.

My only question is, since there is a few degress of difference, do you set
it to where it just goes, high, just goes low, or somewhere in between? I
tried all three today, and quite honestly, I can't "feel" any difference.
