Power gains are up to 40hp to the wheels (55hp crank) on a completely stock vehicle on premium pump gas. \u003cbr\u003e\u003cbr\u003eThe JB4 features a simple plug and play installation harness for easy installation \u0026amp; removal and includes many features not found with any other tune. Including on-the-fly 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 it 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 changing maps, logging, customization, and loading new features as we add them, we suggest adding one of our Bluetooth phone adapters!\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/JB4-PRO-APP-FREE.jpg?v=1760906303\" alt=\"\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cb style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eWirelessly Connect to your JB4: \u003c\/b\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eGrab our all-new \u003c\/span\u003e\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eJB4 PRO\u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e smartphone connection to wirelessly connect the JB4 tuner to your Bluetooth 4.0 compatible iOS or Android device.

The JB4 tuner installs between your car's sensors and its DME\/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel \u0026amp; spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade and is sold in over 67 countries worldwide.\u003cbr\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eIs the JB4 a real tune?\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eYes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and\/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock\/flag your ECU.\u003c\/span\u003e\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003ca href=\"https:\/\/burgertuning.com\/pages\/faq\"\u003e\u003cu\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4-faq-bms-2400_ebe313c1-7832-4131-8f06-a40f5b967b9f_1024x1024.jpg?v=1578019911\" alt=\"JB4 FAQ\"\u003e\u003c\/u\u003e\u003c\/a\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003ca href=\"https:\/\/www.jb4tuned.com\/instructions\/Toyota-Highlander-JB4-Install-Guide.pdf\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1.svg\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e2023 Toyota Highlander Dyno Results (same engine as the Lexus NX, RX, TX 350 2.4L)\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cimg alt=\"2023 Toyota Highlander Dyno Horsepower results specs with JB4 Tune\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4_2023-toyota-highlander_dyno-horsepower_1024x1024.png?v=1673686049\"\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Video\u003c\/h3\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/tqNWgq47A1s?si=3L32mGudFPKMvOF7?rel=0\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":50997555200278,"sku":"Highlander JB4","price":529.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0055\/8753\/3912\/files\/JB4-Tuner-12_68fa8f5e-de1e-4deb-a9ce-4849697e3500.jpg?v=1769706506","url":"https:\/\/np-motorsports.com\/products\/jb4-tuner-for-2022-lexus-nx-rx-tx-350-2-4l-4-cyl-turbo","provider":"NP Motorsports","version":"1.0","type":"link"}
