{"product_id":"performance-tuner-2","title":"Performance Tuner","description":"The Burger N54 JB4 is a high-performance tuner engineered for BMW's N54 Twin Turbo engine, offering a substantial upgrade in power and responsiveness. This plug-and-play device installs easily, connecting between the car's sensors and its DME\/ECU to manipulate performance parameters. It is compatible with all ECU versions and transmission types, ensuring broad application within the N54 engine family.\n\nThis tuner unlocks significant power potential, with claims of up to 80hp at the wheels (100hp crank) on a completely stock vehicle, up to 160hp at the wheels on factory turbos, or an impressive 350hp at the wheels on cars equipped with larger turbochargers. The JB4 is designed to grow with your modifications, accommodating everything from a factory-spec car on pump gas to a heavily modified 700whp drag car.\n\nKey features include multiple on-the-fly performance maps, a stock bypass map, valet mode, support for ethanol fuel (E85), progressive water\/methanol injection readiness, and an auto-tuning map that continuously adjusts to your vehicle's current conditions and modifications. Optional features include in-dash gauges for boost and other parameters, a programmable shift light, and adjustable torque limiting for launches. The JB4 is not VIN-locked and can be easily removed, making it a flexible performance solution. It is designed and assembled in the USA and comes with a 5-year warranty.\n\nNote: This item is not CARB exempt and is not legal for sale or use in California.","brand":"Burger","offers":[{"title":"Default Title","offer_id":52687308423480,"sku":"N54 JB4","price":379.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660190655.webp?v=1784882463","url":"https:\/\/store.motormia.co\/products\/performance-tuner-2","provider":"MOTORMIA","version":"1.0","type":"link"}
