This is a BRAND NEW DiabloSport Predator Tuner for a 2005 Mustang. This tuner has NEVER been turned on. It has NO tunes on it at all. Also have a MAFia (MAF Interface Adapter). Which allows you to use the factory MAF sensor in supercharged or high horsepower applications. ALL of this stuff is brand new and never been used before. I am looking to get 250 O.B.O....All offers taken into concideration.
