Description
The Burger Motorsports JB4 is an advanced plug-and-play performance tuning system designed specifically for the 2018+ Lexus LS 500 3.5L twin-turbo platform. Developed for safe yet substantial power gains, this BETA application delivers increased horsepower and torque without requiring ECU flashing or permanent modification.
Unlike traditional ECU remaps, the JB4 operates as an intelligent inline tuning module that interfaces with factory sensors and CANbus data in real time. This allows precise control over boost pressure and engine parameters while maintaining full OEM drivability, reliability safeguards, and reversibility.
Performance Gains & Driving Enhancement
The JB4 significantly improves vehicle performance across all driving conditions:
- Up to +60 wheel horsepower / +75 lb-ft torque (stock vehicle)
- Stronger acceleration and improved 0–60 times
- Faster throttle response and enhanced mid-range torque
- Additional gains available with bolt-ons, higher octane fuel, or ethanol blends
This makes it one of the most effective tuning solutions for the LS 500 twin-turbo V6 platform.
Advanced Tuning Features
The JB4 system includes a full suite of performance and diagnostic tools:
- Multiple adjustable performance maps for different fuel types
- E85 ethanol blend compatibility
- Boost-by-gear traction control for improved grip
