Description
If you are looking to boost your Chevrolet Silverado 2.7L Turbo's power without the risks of flashing, the JB4 Tuner is the perfect solution for you. The plug and play tuner is easy to install and attaches to two sensors in your engine bay, working with your factory ECU tuning to optimize boost, timing, and fueling for enhanced performance and reduced turbo lag.
Power gains of up to 85whp and 120wtq to the wheels on a stock truck without the risks of flashing!
This plug and play tuner attaches to two easy to access sensors in your Chevrolet Silverado's engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag.
Installation is very discrete and unlike flash remaps which are quick to install but can never be fully removed with a JB4 the vehicle is never aware it's making more than the factory boost or power levels. Fuel economy during normal driving is unchanged and it's compatible with all driving modes including towing.
Unlike other less advanced systems, the JB4 includes CANbus functionality allowing it to take in critical engine data directly from the ECU for real-time tuning. The data includes pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, fuel trims, gear, and much more. Other tuners without CANbus are not able to even monitor this critical engine data no less incorporate it real-time into their tuning algorithms. CANbus allows the JB4 to provide huge power increases with unparalleled power delivery.
The JB4 for Silverado 2.7L Turbo is compatible with both the original and newer high torque engine!
The JB4 includes multiple maps including those for 91 octane, 93 octane, factory tuning, VALET mode, E85 mixtures, and unleaded race gas. In addition, it offers boost by gear settings to improve launches, the ability to read and delete fault codes, and much more. The JB4 is made in the USA and includes a 5-year warranty.
Wirelessly connect the JB4 for the 2019+ Chevy Silverado 2.7 Turbo to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development.
