The Unitronic ECU Upgrade typically raises the power output of the 4.0T to 524 horsepower and 534 lb-ft of torque on 91 octane fuel! Expect improved throttle response and a smoother, more powerful top end with no loss of drivability or reliability.

Unitronic software can be loaded with up to four user selectable Operating Modes as well as Extra Features. Unitronic's Flipswitch technology allows switching of Operating Modes or activation of Extra Features in seconds using the cruise control stalk with no need to purchase external hardware.
