It would be superior in that:
1. its currently in stock and available.
2. My calibrations are not fixed and are fully adjustable.
3. You get multiple tune files and support from me.
I stocked up on pulleys recently and have these on hand ready to ship, 3 custom tunes are included. 93 Octane usually nets 620WHP
