Power gains of up to 30whp and 40wtq to the wheels on a stock vehicle without the risks associated with flashing!
The JB4 is a plug and play performance tuner that attaches to two easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.
JB4 Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Does NOT require flashing the ECU!
The system is fully CANbus equipped allowing the tuning to take in advanced engine data for mapping, logging, and diagnostics. Data channels include boost, timing, air/fuel, fuel trims, throttle, knock control, and much more! Made in USA. 5 Year Warranty.
