Did download without any additional changes yet. Performance has increased. Also sounds better. Very easy to do.

I'll start by saying I was skeptical. First time using a tuner and I know it should help but never really thought it would be all that noticeable. I used the canned 87 octane tune as I use my vehicle for commute by it really did make a noticeable difference. Much more response with better economy, it's a double win for me. Can't imagine what a 93 custom tune would do for it! If your a first time buyer I would definitely recommend you try it out, you won't be sorry.

If your looking to get a programmer but not wanting to mess around with custom setting this is a good choice. If you have an automatic Dodge a programmer is a must as it cleans up the shift pattern and makes towing a much better experience. This programmer also allows you to monitor in real time such things as boost, transmission temperature, etc... You can expand this programmer which is nice if you want to take it a step farther.
