JB Plus Plug-In Power Module for BMW F-Series N20 N26 N55 by Burger Motorsports

Looking for a fast, affordable power upgrade without a remap or coding? The BMS JB Plus plug-in module is a proven piggyback solution for BMW turbo petrol engines N20, N26 and N55 across the F-Series range. It increases boost safely, keeps all factory protections intact and removes in minutes for servicing or resale. Perfect for daily-driven cars that want a sharper punch and stronger midrange torque.

Real gains, factory-safe

• Adjustable boost increase up to 4 psi over stock
• Up to 25 wheel horsepower and 35 wheel torque on N20 and N26
• Up to 35 wheel horsepower and 45 wheel torque on N55
• DME continues to manage timing and fueling for OE-level safeguards
• No change to fuel economy during normal driving

We run this module ourselves and customers consistently report quicker throttle response, stronger midrange pull and a noticeable improvement in overtakes. It is the simplest way to unlock extra performance on BMW TwinPower Turbo petrol models without a full ECU tune.

Why choose JB Plus

• Install in minutes with genuine plug-in connections
• Fully reversible for warranty and resale
• Works with both pneumatic and electronic wastegate vehicles
• One unit auto-detects engine type across N20, N26 and N55 F-Series applications
• All factory drive modes retained
• Lower cost than more complex systems while delivering strong, repeatable gains

Compared with data-logging solutions, JB Plus focuses on straightforward, reliable power. If you want the easiest bolt-on performance upgrade with minimal fuss, this is it.
