Description

The Burger Tuning JB4 is a plug-and-play engine tuner that leverages your vehicle's factory ECU to optimize performance for Mazda models equipped with the SKYACTIV 2.5L Turbo engine. This system safely remaps boost and timing by connecting to two MAP sensors and one MAF sensor under the hood, and utilizes OBDII under the dash for advanced diagnostics and tuning. This tuner is compatible with several Mazda vehicles, including the 2021+ Mazda 3, 2017+ Mazda 6, 2017+ Mazda CX-5, 2016+ Mazda CX-9, 2021+ Mazda CX-30, and 2023+ Mazda CX-50, all with the 2.5L Turbo engine. The JB4 tuner is capable of delivering significant power gains. One source indicates up to 40 wheel horsepower and 50 wheel torque on a stock vehicle. It also offers a 5-year warranty for peace of mind.
