Description
The Burger Tuning JB4 for 2019+ Chevrolet Silverado 2.7L Turbo is the most advanced plug-and-play tuning solution for GM’s latest turbocharged truck platform. With gains of up to 85 horsepower and 120 lb-ft of torque to the wheels, the JB4 transforms your Silverado’s performance without touching the ECU—making it 100% removable and undetectable by the dealer.
Unlike basic piggyback systems, the JB4 features full CANbus integration, pulling real-time engine data such as pedal input, throttle position, ignition timing, AFR, gear, knock activity, and fuel trims to dynamically adjust boost, fueling, and timing. The result is smooth, safe, and reliable power delivery that works in all driving modes—including towing.
Preloaded with maps for 91 octane, 93 octane, E85 blends, race gas, stock mode, and VALET mode, the JB4 allows on-the-fly map switching with the optional JB4 Mobile or JB4PRO adapters. It also supports boost-by-gear, fault code reading/clearing, and advanced data logging. Installation is discreet, takes under an hour, and is fully reversible.
