How to use this tool
1. Import a CSV export from your dyno software — one column for RPM (X), one for power or torque (Y).
2. Select your X and Y columns, then set the RPM range you want to integrate over using the start and end point fields.
3. Choose an integration method — trapezoidal is recommended for dyno data.

Why surface area matters more than peak numbers
A performance gain from modifications can be read off a dyno chart as an improvement in peak power or torque — but this only tells you a small part of the story. The most important metric, far more telling than the gain in peak numbers, is the surface area gained under the curve. Integrating your power or torque curve gives you a direct measure of how broad and usable the power band actually is. Two tunes can show the same peak power figure while delivering completely different driving experiences — the one with greater area under the curve will always feel stronger, respond better, and be faster across a real-world rev range. This tool lets you quantify those gains properly.
