The best thing to do is go to the people you bought your XCAL2 from and ask them these questions. Your dealer (tuner) should be able to provide you with generic settings for most aftermarket parts (like CAIs, etc.), but to take full advantage of the aftermarket parts and the XCAL2 you will need to go the dyno tune route with a custom tune.
