Description
The Burger Tuning JB4 Tuner for the 2019+ GMC Sierra 1500 2.7L Turbo is a plug and play tuner that can boost your truck's power up to 85whp and 120wtq without the risks of flashing. The tuner attaches to two easy-to-access sensors in your engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. Unlike flash remaps, the JB4 is discrete, and the vehicle is never aware that it's making more than the factory boost or power levels.
The JB4 includes CANbus functionality, allowing it to take in critical engine data directly from the ECU for real-time tuning. This data includes pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, fuel trims, gear, and much more. This feature sets the JB4 apart from other less advanced systems that cannot monitor this critical engine data, let alone incorporate it real-time into their tuning algorithms. With CANbus, the JB4 provides huge power increases with unparalleled power delivery.
The tuner includes multiple maps for various fuel and modification levels, including those for 91 octane, 93 octane, factory tuning, VALET mode, E85 mixtures, and unleaded race gas. It also offers boost by gear settings to improve launches, the ability to read and delete fault codes, and much more. The JB4 Mobile connect kit or BMS data cable allows you to wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device or Windows laptop to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware.
In addition to the performance gains, the JB4 is made in the USA and includes a 5-year warranty. The tuner runs as smoothly as stock and is compatible with all driving modes, with no change in fuel economy during normal driving. It's not VIN locked and can be removed without a trace and resold down the road. The JB4 offers a lot more performance, functionality, and safety than your average performance chip, and the rugged JB4 billet aluminum enclosure provides protection.
In summary, the Burger Tuning JB4 Tuner is the perfect choice to boost the power of your GMC Sierra 1500 2.7L Turbo. With its advanced CANbus functionality, multiple maps, boost by gear control, and much more, it provides unparalleled power delivery and performance gains.
