Show original supplier description

The Burger Motorsports JB4 Performance Tuner is engineered for the 2016 and later Infiniti Q50 and Q60 models equipped with the 3.0T engine. This advanced tuning module offers a straightforward, plug-and-play installation by connecting to two readily accessible sensors within the engine bay. By integrating with your vehicle's factory DME, the JB4 effectively remaps boost and timing parameters to unlock substantial performance improvements. This tuner is capable of delivering impressive power gains, with reported increases of up to 100hp and 120 lb-ft of torque at the wheels on a stock Infiniti Q50/Q60 3.0T. The design emphasizes ease of use, allowing for installation without any permanent modifications to the vehicle's existing systems. The JB4 system is designed to work seamlessly with your car's stock ECU, offering a refined performance enhancement.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
