SCT X2R In-Line Performance Device (18300S)
The SCT X2R In-Line Performance Device delivers a simple, plug-and-play performance upgrade for turbocharged gasoline and diesel vehicles. Designed to unlock hidden power without permanent modifications, the X2R can provide up to 30% more horsepower and torque by intelligently optimizing factory engine management parameters. The result is quicker throttle response, stronger mid-range pull, and a noticeably more engaging driving experience.
Unlike traditional tuning methods, the X2R installs as an auxiliary control module that intercepts sensor signals, recalculates optimized values, and sends them to the ECU in real time. This approach enhances performance while retaining factory safety strategies and long-term reliability. In addition to increased power, refined torque delivery and smoother engine behavior can also contribute to improved fuel efficiency, making the X2R ideal for daily-driven performance vehicles.
Engineered to SCT’s high quality and durability standards, the X2R is built to handle demanding driving conditions while maintaining OEM engine protections. Installation requires no specialized tools or mechanical expertise, making it one of the fastest and easiest ways to upgrade performance across a wide range of popular European platforms.
