JB+ Tuner for B38/B46/B48/B58 Engines

The JB Plus is a quick install tuner designed to unlock instant power for BMW and MINI vehicles featuring B38, B46, B48, and B58 engines. This top-rated tuner allows for user-adjustable boost settings, increasing it by up to 4.5 psi over stock. It delivers impressive gains, with claims 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 tuner works by increasing boost pressure, while leaving the factory DME to manage timing and fueling, thus preserving all original safety systems. This ensures reliable performance during normal driving with unchanged fuel economy.

Customers can receive a 100% trade-up credit towards a JB4 by returning their JB Plus within one year of purchase.
