About us

At Truth Dyno & Performance, we don’t just work on classic cars and hot rods—we live and breathe them. Based in Medina, MN, we specialize in Holley EFI tuning, dyno tuning, classic car restoration, Holley EFI conversions, and Holley carburetor tuning, ensuring that every vehicle we touch performs at its best. With over 30 years of hands-on experience, we combine old-school craftsmanship with modern EFI tuning and performance upgrades to keep classic cars running strong.

Our Story: A Passion Turned into a Profession

At Truth Dyno & Performance, our journey started with a love for classic cars, muscle cars, and hot rods. With a strong background in computers and technology, we saw the opportunity to bridge the gap between modern performance tuning and classic car restoration. From Holley EFI installations to Mustang chassis dyno testing, we take a data-driven approach to performance upgrades and tuning.
