I've been reading about this for the past few days, and it sounds too good to be true! But those who have done it say it is true...20-30hp gains, depending on the car and its mods, and the tune automatically shifts maps when you switch from pump gas to E85, and back again! This looks really good to this California boy! $850(kit parts + UM tune) plus labor.
Anyone have more real world stories to tell?
