Re: Post electric fuel MPG
Had the same thing happen and I was told that it was because you were now able to supply fuel to the heads in a constant volume. I was told that mechanical setup causes a ripple effect in the fuel thats in the rail when the injector fires, causing some what of a starving effect. An electric system provides constant pressure in the rail and can keep supplying instantaneously after the injector fires reducing if not eliminating the ripple effect. Hopefully that makes sense. Bottom line is I saw a slight decrease, about 1.5-2mpg in daily driving but no loss on the higway.
