I have a hondata stage 3 but I want to keep it. However, the person I had tune it had tuned it all wrong for my setup. Since he didnt have my car there because I was out of state he had to just give me a base program. Also do to the fact of where I live no one in my town or state can tune a hondata. Since dyno tuning is the only way I can get my power I have to change to the AEM EMS because the person in my town knows that system and has the dyno. Unforuately, if I were to keep the hondata he wants to charge me for the time to learn the system.
