check overkill website for PCM tune.
Other on here have used them.

do they even still make chips? When people say tune, you can either buy a pre programmed handheld from someplace like super chips or Diablo, or you can get a custom tune. I have had a pre programmed tune and I've had a custom tune. for simplicity and ease of use, there's nothing wrong with a pre programmed tune. I currently have a custom tune, but that is only because the tuner was convenient to my location and things can be a little trickier when dealing with turbo boost. you don't want to overdo it.

Box tune or overkill. Stay away from the chips.
