Using technology similar to our PCM, the JET module provides the ultimate in power tuning and optimal mileage. Point-by-Point air/fuel ratio, ignition advance, and various other tuning points provide performance gains of up to 25hp. JET performance chips tune your transmission for better performance, and improves your spark timing by using Dynamic Spectrum Tuning (DST). With all of those optimized to peak performance you will see an increase in horsepower and torque. The JET power control module stage 2 works with vehicles that have light to heavy modification to them. For example you can have Performance air intakes, headers, exhaust, bored pistons, and many other modifications.
