When using the X-Cal 2 and changing tunes (like going from the 87 to the 91 or 93), is it necessary to return to stock before changing to the higher octane tune, or can you just load the higher tune?

If this has been covered in another thread, forgive me for being redundant. I didn't have any luck finding it.
