Vehicle / Gear Estimates

The dyno curve is calibration-based: stock engines anchor to known factory crank ratings, and changes are applied as relative airflow/compression/boost/fuel modifiers. Real dyno results still depend heavily on tune, dyno type, exhaust, weather correction, ring seal, converter, accessories, and fuel quality.
