I use Heintz Performance and I highly recommend. They will be doing all of my futures upgrades (forced induction is next). Really good guys, they worked with (actually bought the business from) my former tuner who I used for 15 years. Here is the owners personal number.(Jeff Heintz) 704-791-4663. Send him a text and tell him "Rick Belden" referred you. May I ask you name and I will let him know you will be reaching out.
