Dyno results

Peak power gains do not always tell the whole story! It's important to look at power gains across the entire RPM range / dyno curve, A.K.A. power "under the curve." Power gains under the curve will have a greater impact on driving experience. This is because gains under the curve impact the broader usable powerband, whereas peak power is momentary - only at one point in the RPM range.

If peak gains are 5% while max gains under the curve show 20%, this +20% increase is a better reflection of how your driving experience will change (you'll certainly feel that increase!). You want to feel the difference in the seat of your pants, and this is where power under the curve plays usually the biggest role.
