Burger Motorsports BMS JB+ Plug & Play Piggyback Tuner for BMW N54 Twin Turbo (1M, 135i, 335i/335is, 535i, Z4 sDrive35i, X6 xDrive35i) - +30whp +40wtq, Adjustable +3-4 psi

Instant Turbocharged Power for BMW N54 Models with the BMS JB Plus

Want easy, reliable gains from your 3.0 twin‑turbo straight‑six without a remap or coding. 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. It is the ideal first upgrade if you want stronger mid‑range punch, faster throttle response and effortless overtakes with a simple install you can remove at any time.

Set at a baseline increase of +3 psi, typical results are around +30 wheel horsepower and +40 wheel torque. 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.

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. If you want a no‑nonsense power upgrade that avoids ECU flashing, this is the one.
