The ECM tuner is designed to plug in and tune the vehicle – No gauges included. The ECM tuner is also CAT, CUMMINS, DETROIT or Paccar specific. The GT works on all the engines and includes a mount and gauges that monitor critical information. Both Devices will change the speed limiter and read/clear/save DTCs.
