I would probably not move the spark adjustment, you can actually create detonation (pinging) if you modify the table too much. The trans shift you can modify depending on how you feel your vehicle drive after it has been programmed. You can make it shift harder, softer or delay, advance when the vehicle shifts (assuming the vehicle is automatic). All these adjustments are adders to what has already been modified in the preloaded tunes.
