Bumping this back up to see if those who purchased have the full kit installed yet. Curious to hear overall feedback and thoughts on the sound difference.
My understanding is they build a new PCM file based off your VIN and load it to a blank PCM which they acquire for you. You will have the red light unless you send in your original PCM or cloned PCM.
I am so happily confused by the prices for these things. The headers for my Mustang cost as much as taking my Jeep to a full stage 2 with exhaust. This is lovely.
