This system processes ultra-fast digital sensor signals with zero latency, delivering a significantly enhanced driving experience. Power gains of up to 130hp to the wheels are achievable on a stock vehicle using 91 octane or better fuel, with even higher gains possible when using ethanol blends.\n\nThe JB4 is designed for straightforward installation and removal, utilizing a plug-and-play harness that connects between the vehicle's sensors and the DME\/ECU. It offers a comprehensive suite of features, including real-time data logging of up to 40 engine parameters, built-in fault code reading and deletion, and boost-by-gear control for improved traction. Map switching between factory and performance maps can be done on-the-fly via the free JB4PRO smartphone app, which also supports firmware updates and advanced data analysis.\n\nConstructed with a durable billet aluminum enclosure and backed by a 5-year warranty, the JB4 ensures reliability and longevity. It is not VIN-locked and can be fully removed, preserving the vehicle's original condition. The JB4 is compatible with all driving modes and does not impact fuel economy during normal driving. This system is specifically designed for the exact vehicles listed below and does not plug into previous years' B48\/B58 engines due to different connector types.","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":52687321792824,"sku":"JB4-B48B58-OBD","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661174826.webp?v=1784882648","url":"https:\/\/store.motormia.co\/products\/jb4-performance-tuning-system-for-b48-b58-engines","provider":"MOTORMIA","version":"1.0","type":"link"}
