JB Plus Tuner

The Burger Motorsports JB Plus is a quick install tuner designed to enhance performance for BMW and MINI vehicles equipped with B38, B46, B48, and B58 engines. This device allows for user-adjustable boost control, capable of increasing boost pressure by up to 4.5 psi over stock settings. It is engineered to deliver significant power gains, with reported increases of up to 30 wheel horsepower and 40 wheel torque for B48 engines, and up to 40 wheel horsepower and 50 wheel torque for B58 engines. The JB Plus integrates seamlessly with the vehicle's factory systems; it maintains normal fuel economy during regular driving and automatically detects the installed engine type. All timing and fueling are managed by the original DME (Digital Engine Electronics), ensuring that factory safety protocols remain active and unchanged. Burger Motorsports offers a clear upgrade path for users who wish to progress to more advanced tuning. The JB Plus can be traded in for a full credit towards the purchase of a JB4 tuner within one year of the original purchase. This tuner is manufactured in the USA and comes with a 5-year warranty, reflecting the company's commitment to quality and durability. Additionally, the B58 JB Plus tuner has received CARB Approval (Executive Order No. D-744-4) for specific 2016-2018 BMW applications, including the 230i, 330i, 430i, 530i, 340i, 440i, 740i, M240i, and X1 models.
