What sort of improvements can I expect?

The tune is designed to give a conservative yet exhilarating 10% improvement in performance. With this Hondata performance upgrade, your Accord will match the performance of many more expensive luxury cars.

Your Accord gains anywhere from 10 to 40 hp everywhere,  with the maximum gains not at the top of the rev range, but where you need it most at the low end of the rev range. Rapid acceleration is just a quick flex of the throttle pedal away. 91 or higher octane recommended.
