OST Dyno

Based in Slippery Rock, Pennsylvania, just outside Pittsburgh, this performance facility concentrates on Gen 3 Hemi and Hellcat platforms—a niche that demands precision, reliability, and real‑world endurance. The team blends racing heritage with engineering discipline, delivering horsepower that performs on street duty and through track sessions alike. An in‑house workflow centralizes parts sourcing, fabrication, and tuning under one roof, reducing lead times and ensuring consistent, high‑quality results. A state‑of‑the‑art AWD Mustang dynamometer powers the tuning process, enabling precise fuel, ignition, and boost calibrations across a variety of setups. In practice, gains are validated with repeatable data and hands‑on testing on both road courses and the drag strip.

Core services include:

• In‑house dyno tuning on an AWD Mustang dyno for precise mapping
• Remote tuning support for Mopar and GM vehicles via email
• Custom Hellcat, Demon, and Trackhawk packages with track‑proven gains
• Comprehensive performance parts procurement, installation, and calibration
• Carbureted vehicle tuning (Holley focus) with full diagnostics

What sets this shop apart is the one‑stop model: sourcing, fabrication, and tuning are coordinated under a single roof to streamline projects and keep goals aligned with execution. With more than four decades of performance automotive and racing experience, the team delivers measurable improvements while upholding reliability. A protective front‑end wrap during service reflects a careful approach to safeguarding customers’ investments. The shop also partners with clients to tailor packages for street usability and track days, ensuring drivability isn’t sacrificed for power.
