Power gains of up to 100whp 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 the 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 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.

JB4 V1 and V2 Map Guide:
Map0: Fully disable JB4
Map1: +3.5psi peak over stock, default map, 91+ octane
Map2: +3.5psi peak, less top end taper, more aggressive version of map1.
Map3: +4psi peak, suggested for 93+ octane and/or modified trucks
Map4: Low boost VALET map
Map5: +6psi peak, suggested for 30% E85 mixtures and/or unleaded race fuel
Map6: Custom tuning map user adjustable
Map7: +7psi peak racing map for unleaded race fuel

Check your sensors to confirm the required harness before ordering!

JB4 systems use one of four different wiring harnesses. You'll need to locate and identify both the charge pipe and intake manifold MAP sensors, generally on the charge pipe leading into the throttle body, and under or behind the plastic engine cover on the manifold directly, to determine which JB4 harness your vehicle requires.

1) V1 Harness: Two V1 sensors, generally found on 2014 and earlier models
2) V1.5 Harness: One V1 sensor, one V2 sensor, generally found on 2015-2016 models
3) V2 Harness: Two V2 sensors, generally found on 2017-2020 models
4) V3 Harness: One V3 sensor, one V2 sensor, generally found on 2021+ models

Sensor arrangements are vehicle specific, so while our model year guide gives common applications, there are some 2017-2020 vehicles that use V1.5 harnesses, some 2021+ models that use V2 harnesses, etc. Check your vehicle prior to ordering.

What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade and is sold in over 67 countries worldwide.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.
