You will definitely feel a difference with a re-programmer! The Bully Dog is one of the most popular. It has a lot of great features. I opted for something simpler, a Superchips tuner. Even if you just go with the 87 octane performance tune, you will notice a significant improvement in power. My only complaint with it is that they eliminated the wide open throttle restriction disable on the latest software versions. It also allows you to tweak ignition timing and idle speed and can read OBD II codes, among a few other things. Prices have dropped over the past couple of years. Uprev is probably one of the best, but it's not cheap and I would only recommend it if you are doing a lot of performance mods to your engine.
