I originally bought a DiabloSport Predator, but then sold it and got a SCT Xcal 2 because I was disappointed with the after sale support. However, as others have said, find the person who will supply your tunes first. It should be someone who will continue to supply you with tunes later after you make mods that you are not expecting to make at this time. Then ask that person which of the two you should buy.
