The Burger Motorsports JB Plus is a clip‑in performance module that adds serious shove to N54‑powered BMWs while keeping the factory ECU untouched.

You can also raise it up to +4 psi for extra punch. It works with all software revisions and gearboxes, including manual, automatic, rear‑wheel drive and xDrive. Dyno proven, road tested and customer approved.\n  \u003c\/p\u003e\n  \u003cp\u003e\n    We run this unit on our own N54 cars and our customers consistently report crisper response, harder mid‑range pull and smoother, more linear acceleration.
