Description
Fabspeed XperTune for the McLaren MP4-12C recalibrates sensor strategies, air/fuel targets, and boost control to increase horsepower, torque, and overall drivability while maintaining reliability. It offers maps for stock cars and builds with Sport Cats, bypass pipes, exhausts, or upgraded turbos, yielding harder spool, stronger midrange, and a cleaner pull to redline.
