so adding turbo throws off the gas mileage by how much?
Fuel economy in the Slingshot is measured by injector pulse. So when you add a larger injector that pulses less than the factory you will actually see the fuel economy increase which is a false reading. However, I know with both DDM and ZZP, we both have corrected that data in our supplied tunes so your mileage really shouldn't change much unless you keep the pedal all the way down with the new found power.
