JB+ B46/B48/B58 Tuner

The Burger Motorsports JB Plus (JB+) is a quick install tuner specifically designed for 2020-2026 Toyota Supra Mk5 models equipped with B48 or B58 engines. This popular and well-proven tuner allows for user-adjustable boost pressure, increasing it by up to 4.5psi over stock. This can result in significant power gains, with reports of up to 40 wheel horsepower and 50 wheel torque on the B58 Supra engine. The JB+ works by seamlessly integrating with the vehicle's DME (Digital Motor Electronics), which continues to manage engine timing and fueling. This preserves all factory safety systems, ensuring reliable operation during normal driving, with fuel economy remaining unchanged. Installation is exceptionally simple and can be completed in under a minute, requiring no special tools and being fully reversible. The unit automatically detects the engine type, making it compatible with any B48 or B58 F-series application. Burger Motorsports offers a trade-up credit towards their more advanced JB4 tuner for those who wish to upgrade later. This tuner is designed and assembled in the USA and includes a 5-year warranty. It is compatible with the 2020-2026 Toyota Supra Mk5 B58 3.0L 6-cylinder Gen2 and the 2020-2026 Toyota Supra Mk5 B48 2.0L 4-cylinder Gen2.
