2005-2009 Cobalt 2.4L LE5 Performance Tune

DOLLAR FOR DOLLAR THE MOST POWERFUL MODIFICATION YOU CAN BUY FOR YOUR 2.4L COBALT SS OR COBALT SPORT.

It seems that since the 2.4L Cobalt SS was not supercharged that it was not given as much attention as its faster Super Sport brother, but we have always supported the LE5 powered Cobalts.

Our performance tunes not only add a significant amount of power ALL across the power band, but we also remove the torque management tables that would otherwise prevent the engine from putting all of that new-found power to the ground.

In addition to the power gains, Cobalts equipped with the 4-speed automatic transmission also benefit from a complete retune of the transmission control module. With the RPM-Motorsports Stage 1 Tune you will experience higher RPM shift points, Increased shift pressure, and faster shift times. By reducing the shift times by approximately 0.25 seconds per gear change, your car would be faster down the quarter mile and faster in 0-60mph tests as well.
