{"product_id":"jb4-tuner-8","title":"JB4 Tuner","description":"The Burger Motorsports JB4 Tuner is a highly featured tuning system engineered specifically for the Toyota Supra Mk5 (A90\/A91). It is capable of delivering significant power gains, with reported increases of up to 80hp to the wheels (100hp at the crank) on a completely stock vehicle running on pump gas. For those who have installed bolt-on parts, use higher octane fuel, E85 mixtures, or larger turbos, even greater performance increases are possible.\n\nInstallation of the JB4 is straightforward thanks to its plug-and-play harness, allowing for quick setup and removal without leaving a trace. This tuner boasts a wide array of advanced features not typically found in competing products. These include on-the-fly map switching directly from the dashboard, the ability to limit boost by gear to improve traction, progressive water\/methanol injection support, built-in data logging capabilities, and fault code reading\/deletion. It also offers direct EWG control to prevent throttle closure with exhaust modifications and control for the exhaust flapper.\n\nWhile the JB4 is designed to be a standalone modification, users can further enhance its functionality by connecting it wirelessly to an iOS or Android device via the JB4 Mobile connect kit or to a Windows laptop using the BMS data cable. These options enable detailed vehicle and tuning data analysis, performance map adjustments, and firmware updates. A separate JB4 Mobile app purchase is required for these advanced features. It's important to note that the in-dash commands for map and setting changes are not yet developed for the Supra JB4; therefore, a mobile adapter or data cable is necessary for any adjustments.\n\nThe JB4 is compatible with both the 2.0L 4-cylinder and 3.0L 6-cylinder engines found in the 2020-Present Toyota GR Supra Mk5, including A90 and A91 models. However, 91 octane fuel or higher is recommended for optimal performance gains. The unit is housed in a rugged billet aluminum enclosure and is made in the USA, backed by a 5-year warranty.","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":52687321989432,"sku":"JB4-A90-SUPRA","price":599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661174840.webp?v=1784882651","url":"https:\/\/store.motormia.co\/products\/jb4-tuner-8","provider":"MOTORMIA","version":"1.0","type":"link"}
