Toyota Supra MK5 GR A90/A91 JB4 Tuner 3.0 B58 & 2.0 B48 - Burger Motorsports Plug & Play Piggyback/Performance Chip, ECU Power Module & Tuning Box, Boost Controller, Up to +80whp - Remap Alternative - BMS171

JB4 Power Module for Toyota GR Supra A90 B58 3.0 and B48 2.0 | Part No. BMS171

Turn your A90 Supra into the car it should have been from the factory with the Burger Motorsports JB4. This add-on engine controller delivers huge gains on the 3.0 B58 and 2.0 B48 turbocharged platforms while keeping factory smoothness and reliability. Expect around 80 wheel horsepower uplift on a standard car with premium fuel, with even stronger results when paired with popular bolt-ons and ethanol blends. No ECU flash required and no permanent changes. Install, enjoy, remove at any time.

We use the JB4 ourselves and our customers consistently report sharper throttle, massive midrange torque and harder pull to the limiter, along with improved 0 to 60 and quarter mile performance. It is the smartest remap alternative for the GR Supra if you want real gains, genuine features and simple install.

Control, maps and connectivity

Map changes, logging and firmware updates are handled via the optional JB4 Mobile Bluetooth Connect Kit for iOS and Android, or the BMS Data Cable for Windows laptops. The JB4 Mobile app is a separate purchase. For the Supra platform, in dash map switching is not available so use the Bluetooth adapter or data cable to change settings.

Real world gains on the GR Supra

On a standard A90 running quality petrol 91 octane or higher, the JB4 adds serious power and torque with stock like drivability. Add a high flow downpipe, freer flowing intake, cat back exhaust or upgraded intercooler and the controller extracts even more performance. Running higher octane or ethanol blends further increases results. Smooth, strong and repeatable.
