I recently bought a Hondata but have no idea how to use. My honda civic si 2015 has an aftermarket exhaust and aftermarket intake. What could I possibly do with the Hondata if anything?
Take it to a tuner if you dont know what you are doing. But wait until you have real power adders such as any form of boost of if you decide to the NA route...once you change cams you will def need a reliable tune.
