Dyno Tuning Services

Unlock Every Horsepower. Dial in Performance with Precision.

At Hargett Automotive & Performance, we don’t just tune cars—we calibrate machines for peak performance. Our state-of-the-art chassis dyno allows us to safely and accurately simulate real-world driving conditions while precisely adjusting your vehicle’s calibration to get the most out of your setup.

What We Offer

✅ Custom Dyno Tuning (Gasoline & Flex-Fuel)

• From naturally aspirated street cars to high-horsepower forced induction builds, we tune for maximum safe power, driveability, and efficiency.

• Supported ECUs: Ford, GM, Dodge, and a range of standalone systems (HP Tuners, Holley EFI, etc.).

✅ Forced Induction Tuning

• Supercharged, turbocharged, or compound boost—whether it’s mild or wild, we’ll tailor your tune to optimize fueling, ignition, boost control, and safety limits.

✅ Race Car Calibration

• Track-focused setups require different strategies. We provide power delivery tailored to track conditions, launch control strategies, and data-driven adjustments to gain tenths where they count.

✅ Transmission & Shift Tuning

• We fine-tune transmission behavior (shift points, firmness, torque management) for optimal performance whether it’s a 6R80, 10R80, or built 4L80E.

✅ Vehicle Diagnostics & Baseline Runs

• Not sure what your vehicle is making or how it's performing? We offer dyno pulls with detailed AFR, boost, and power/torque readouts.

✅ Safe & Repeatable Testing Environment

• Climate-controlled, load-bearing dyno cell for consistent, accurate results without risking your build on the street.
