Over the weekend I calculated 11 mpg driving from Boise to Huntington, OR pushing a nasty head wind. I got better gas mileage in fifth than sixth. Today, from Baker City to Boise 16 mpg; 70 in OR and 80 in Idaho. I wonder if running at a slightly higher rpm so I get the benefit of the supercharger. Once boost builds the LC just wants to go faster. Maybe 4.88s are the solution.
I calculated 16.5 mpg on a mostly highway/country road run from Fredericksburg VA to Manassas and then up to Shepherdstown WV, based on gps distance and number of gallons to fill the tank. This is with stock gears, sea level altitude, and no noticeable headwinds, running 275 70 18's. I do have arb armor, a hidden winch mount, prinsu roof rack and sliders, so not super heavy, but also not stock.
Anyone have real world data on mpg with the supercharger? The 24mpg states at the beginning of this thread made me lol. I’m assuming a 1-2mpg loss is more typical.

Yeah that gas mileage blows my mind too. I got rid of a 2014 Porsche AWD twin Turbo recently that usually got about 10 mpg in town since I couldn't keep from punching it constantly , and on the highway of course that light car would get 25 or 26 doing 75. A turbo is also more efficient since it isn't driven by the engine. So very surprising it worked out so well for you. Sounds awesome. Glad to see people trying things. Increased power and gas mileage must be nice.
I have a feeling the tune helped a lot. What gears are you running?
