Custom Dyno Tuned By Phonsy Mullan
Every vehicle at GM Motorsport is individually custom dyno tuned by the legendary Phonsy Mullan, a true pioneer in LS engine development with decades of hands on experience.
This isn’t a generic file or a “one-size-fits-all” calibration. You won’t find this level of expertise on your car anywhere else. Phonsy has been tuning and engineering performance parts for LS engines since their inception, delivering results backed by real-world testing, innovation, and proven performance.
A current two-time V8 Superboats World Champion and the leader of the GM Motorsport race team for over 15 years, Phonsy applies championship-level precision to every vehicle, ensuring each tune is refined, reliable, and built for maximum performance.
