Performance Module

By optimizing the air and fuel mixture, it ensures a more efficient combustion process. This module safely operates within factory parameters to deliver noticeable performance improvements and a welcome increase in throttle response for better control. The process is described as a simple 5-minute installation. The package includes the PCR Performance Module and a full, vehicle-specific installation guide with diagrams. Additionally, customers receive 24/7 technical support. Unlike some high-cost programmers that can overwrite the ECU and potentially void the factory warranty or cause premature part failure, the PCR Performance Module sends data directly to the ECU without overwriting it. This means it will not void your warranty or cause premature wear. If you wish to revert to factory settings, simply unplug the module, leaving no trace. The chip is compatible with various Buick Regal model years, including 1993-2004 and 2011-2017, across different engine sizes such as the 3.8L V6, 2.0 Turbo 4 Cylinder, and 2.4L 4 Cylinder.
