Stealth Module 🕵️

  • Detectable? No. Be sure to remove the module before taking your vehicle in for service.
  • Impact of Installation? None! The Stealth Module plugs directly inline to the manufacturer connections.
  • Potential of engine damage? We work within the stock safety parameters set from the factory.
  • More low to mid-range power, improved drivability, smoother more predictable power all while leaving emissions intact and staying within the vehicles factory set safety parameters.


  • Detectable? Yes. Traditional tuners leave a footprint on the ECM regardless if it is removed. Traditional tuners will void your vehicles warranty.
  • Impact of Installation? Yes. Splicing of wires and other modifications are usually necessary.
  • Potential of engine damage? Yes. A tuner can cause the EGT's to be too high, create higher cylinder pressures
  • Pushes the truck outside of the factory set safety parameters. Will cause excessive wear on vehicle parts by changing injector timing and duration, throttle input mapping and temperature limits.
