Sport Tuner - Cadillac 14-15 CTS V LME/AIW

The Sport Tuner for Cadillac 14-15 CTS V LME/AIW by LIVERNOIS MOTORSPORTS is a purpose-built engine control module tuner engineered for serious performance enthusiasts seeking measurable horsepower and torque gains on the fifth-generation CTS-V. This tuning platform targets owners who demand more from the factory LSA supercharged powerplant without compromising reliability or drivability. Livernois Motorsports has invested years of dyno and street testing to deliver calibrations that unlock the platform's true potential while maintaining OEM component integrity.

This Sport Tuner module works by optimizing fuel timing, boost pressure mapping, and ignition curves specific to the LSA 6.2L engine's capabilities, translating to significant gains across the RPM band. The tuning software leverages real-world testing data from the supercharged architecture to safely push beyond factory conservative parameters—particularly effective on vehicles running quality 91+ octane fuel. The compact design (6.5 x 3.5 x 7 inches) allows straightforward installation in the engine bay, and the tuning file addresses both naturally aspirated efficiency at low RPM and sustained supercharger performance under load, resulting in responsive throttle mapping that enhances driver experience without sacrificing driveline longevity.

CTS-V owners targeting track duty, weekend performance driving, or aggressive street applications will see the most benefit from this tuner, particularly those running supporting modifications like quality fuel octane or upgraded breathing components. Installation requires minimal downtime, and the tuning integrates seamlessly with the factory PCM architecture on 2014–2015 model year vehicles equipped with either the LME or AIW engine code variants. This is the ideal solution for Cadillac enthusiasts seeking bolt-on power without major engine work, offering the kind of transparent performance gains that justify investment in a proven platform.
