Right now I have a few different tunes. A Tow tune and a Power Tune. Initially I had a great MPG tune but of course as the power was turned up the MPG dropped. Now that it's close to the power output I can start another tune. Currently running E30 fuel for a Power tune which of course lost me 5 mpg minimum. Soon I will go back to the FE tune and normal 91 octane fuel.
Most interested in Aero for the front Air Dam now as part of build.
Engine Cu In dropped from 352 to 213.
