The Standard Xcelerator series tuner was specifically designed to provide better throttle response, shifting characteristics, and add big power without the need for expensive fueling and air upgrades. It provides five power tuning levels of additional horsepower and torque (40 to 225 hp depending upon model). The best part about the PPE Standard Xcelerator is that it will optimize a stock engine’s performance; and works especially well for those which have added items such as a free flowing exhaust and a cold air intake system. Another advantage of the PPE Standard Xcelerator is that if you eventually want the benefits of our Hot+2 E.T. Xcelerator Race models then, it is possible to upgrade the software.
