Power gains are up to 100whp to the wheels (125hp crank) on a completely stock car on 93 octane, and even higher with ethanol fuel mixed in!\u003cbr\u003e\u003cbr\u003eThis new JB4 BMW tuner is specifically designed for the latest Gen 3 B48\/B58 variant and is capable of processing the new ultra fast SENT digital sensor signals in real time with zero latency. The JB4 features a simple plug \u0026amp; play installation harness for easy installation \u0026amp; removal and includes many features not found with any other tune. Including on the fly in-app map switching between factory and various performance maps, boost limiting by gear for improved traction in lower gears, progressive water\/methanol support, built-in data logging, built-in code reading, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.\u003cbr\u003e\u003cbr\u003eRemember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization, but for those who are interested in logging, adding new features as we post them, etc, we suggest the Bluetooth mobile phone adapter.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/JB4-PRO-APP-FREE_1024x1024.jpg?v=1760906303\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWirelessly Connect to your JB4: \u003c\/b\u003e\u003cspan\u003eOur all-new \u003c\/span\u003e\u003cstrong\u003eJB4 PRO\u003c\/strong\u003e\u003cspan\u003e smartphone connection is included to wirelessly connect the JB4 tuner to your Bluetooth 4.0 compatible iOS or Android device.
