Do yourself a favor and get the Power Commander. The HMF is a el cheapo Dobeck programmer. You're very limited on what you can do. You can only add fuel, not lean out the mixture. If you ever do any more to the engine in the future, the HMF will not support it. The Power Commander will. You have total control over the map with the Power Commander. The HMF is pre loaded. Single plug and play with USB map loading.
