Yes...possibly no. It depends. The more RPMs you turn, the higher the gain (the faster we turn the accessories, the more we stand to gain by slowing them down.) The slower your car, the more you gain (tenths are harder to come by the quicker you go.)
But generally speaking, yes. About a tenth and a MPH.
