The TS Performance Stryker is based on the same platform as the TS Performance MPHD. It connects to the injector harness on the engine and monitors the fuel delivery system to determine when extra power and torque is needed. The power increase can be controlled by a switch that can be mounted inside the cab and can be adjusted while driving. You can expect to see over 100HP gain and 2-3MPG increase in fuel economy. All TS Performance products come with a Lifetime Warranty.
