Description
The Burger Tuning JB4 for 2023+ GMC Canyon 2.7L Turbo is the most advanced plug-and-play performance tuner available for your turbocharged Canyon. Delivering up to +85whp and +120wtq on a stock truck, the JB4 improves acceleration, towing power, and throttle response without the risk or permanence of ECU flashing.
With full CANbus OBDII integration, the JB4 reads critical engine data—like AFR, ignition timing, knock detection, gear, pedal position, and more—in real time, using that information to adjust boost, timing, and fueling for maximum safe performance. Built-in safety protocols reduce boost if the engine overheats, runs lean, knocks, or overboosts.
Choose from 8 preloaded maps for 91 octane, 93 octane, E85 blends, race fuel, stock mode, and VALET mode. Additional features include boost-by-gear control, fault code reading/clearing, and the ability to log and view up to 40 engine parameters through the JB4 app.
With the optional JB4 Mobile or JB4PRO adapters, you can wirelessly change maps, log runs, update firmware, and analyze performance directly from your smartphone. Installation is fully reversible, requires no cutting or splicing, and leaves no trace when removed.

What is a JB4?
The JB4 is a cutting-edge plug-and-play tuning system for turbocharged vehicles. Installed between your vehicle’s sensors and ECU, it optimizes performance by modifying boost, timing, and fueling based on real-time data.

With free firmware updates, active community support, and quick removability, the JB4 is the gold standard in turbo performance tuning—perfect for Canyon owners who want more power, better drivability, and towing confidence without sacrificing reliability.
