I was referrinjg to lugging the engine- - - -even a little bit- - - -which causes the manifold vacuum to drop precipitously- - - - -causing the power valve to open and run full rich. People get so hung up on OD transmissions and low RPM at cruuise speed that they totally ignore the advantages of letting the engine rev and keeping the manifold vacuum high- - - -the way the engineers designed it to do. The timid souls with lace on their drawers are so afraid of a little fan noise that they're willing to sacrifice 3-4 miles per gallon so they don't have to listen to it.
