I recently got a Diablo sport on lightning rodder and it was only 85 shipped. The guy said it was unlocked so I jumped on it. Turns out it wasn't unlocked and the guy was cool about it and gave me my money back and let me keep it. So here is where I stand I have the diablo but no usb cable. The tuner I have i think is older so I am wondering for you guys with multiple tuners would do. I am wondering do I pay to unlock it but then have know way to update it or can I get a usb cable for it? Lastly do I skip diablo and go with sct. What do you guys think.
