I have an SCT X3, it doesn't have any tunes and isn't VIN locked. Works great and is in great shape! $240 shipped/paypal
Let me start by saying Im not too familiar with this stuff. Is this limited to how many tunes or how many times you mess with it? Can I put on exhaust on and tune it, then later put intake on and tune it without having any limitations as too how many times? Thx
