since you have to spend a grand+ for the pcm and tuner. Id dyno tune it. Jay gets it close but dyno gets it better

I have full faith in Jay. The man is a mad scientist with these Mopars. I'd rather have a Mopar guy tune my car than someone that tries to do it all. Keep in mind I don't live in a big city where there's tuners everywhere. The few that are around here are mainly LS/LT guys.

You will be happy with a custom tune and that gives you the flexibility to easily do other mods and then have a new tune made
