If you're using a buddy to help you burn a chip and he'll do it as a hook up then I highly recommend that you get everything installed the way you want it and get it tuned. Going back and forth to him may end up exhausting your connection with the person. Get your HCI set up and your fuel components and get it dialed in. Later when you're ready for boost you can then get it re-tuned.That’s a good question! I have a friend who uses sct and said he could burn a chip for me to tune it. Now I have no clue on any of this tune stuff, what I need etc etc. I’ve seen ppl talk about the A9L is that something I need or is that a stock computer that our Cars already have?
