I am currently running a SCT flip chip w/ custom tunes. I've been looking at the new SCT Livewire. Has anyone had any experience w/ it yet?? Can I keep my current tune and transfer it over to the SCT Livewire or do I have to get a new tune programmed into the device? I'm fixxing to put on my nitrous so i'll need a tune for that anyways. Check it out on SCT's website.
