Bully Dog B3X In-Line Performance Device for 2024 Toyota Tacoma & 4Runner (2.4T) + 20
Bully Dog B3X In-Line Performance Device – Introduction
Toyota’s newer turbo platforms (2.4T and 3.5T i-Force / i-Force Max) offer solid performance from the factory, but many owners are looking for stronger mid-range torque, improved throttle response, and better drivability without committing to a full ECU reflash.
The Bully Dog B3X In-Line Performance Device is designed as a plug-and-play solution that installs inline with factory sensors and the ECU. Instead of rewriting the ECU, the B3X continuously monitors engine data and makes real-time adjustments to optimize performance. The result is quicker throttle response, increased usable power, and improved torque delivery, especially in everyday driving and towing scenarios.
Because it does not permanently alter the ECU, the B3X is positioned as a lower-risk, reversible upgrade compared to traditional tuning methods, while still delivering noticeable gains. Key Highlights
Inline performance device (no ECU reflash)
Plug-and-play installation
Real-time optimization of engine parameters
Improved throttle response and mid-range power
Software-updatable via Windows PC
