The GT Gas tuner is very popular with Jeep owners. Here are five ways a Bully Dog GT tuner can take your Jeep's performance to the next level.

  • Reach deep for more horsepower and torque. The Bully Dog GT tuner allows you to adjust key parameters like transmission shift points and throttle response to inspire peak performance tailored to the way you drive.
  • Make sure your gauges read right. Changes to gear ratio and tire size affect speedometer, tachometer, and odometer accuracy. Your tuner provides gauge readings that are adjusted for modifications you’ve made to your Jeep.
  • Put an end to constant dash alerts and chiming. Sometimes the demands of the trail mean you need to air down your tires to get proper traction on uneven terrain. With the GT programmer, deactivate the TPMS when you’re aired down, and reactivate it when it’s needed, in more normal driving conditions.
  • Get more power in idle. Jeep sets your idle RPM at a level that combines battery charging power with fuel efficiency. The Bully Dog Gas Tuner allows you to increase idle RPM to provide power for your winch when it’s needed, so you can tackle difficult terrain without fear, and still keep fuel costs in check.
  • Adjust to difficult trail conditions on the fly. Make changes on the fly to adjust to trail conditions- turn off your engine fan when fording a river, disconnect sway bars, or lock axles for safety, traction, and stability on uneven terrain. The Bully Dog GT Tuner also offers a simple way to completely disable traction control in snowy, icy, sandy, or muddy conditions.
