In the Transmission Only tune, you're probably OK with that spark advance, since the tune itself has not modified the engine parameters at all. I would be VERY careful about trying to advance the spark on either the Level 2 or Level 3 tunes though. The spark has already been adjusted in those tunes for best performance.
