Yesterday i sent my comp box back to have it upgraded to the drag, since they have the $50 promo. I am thinking about getting a smarty to stack with it and am wondering how to run it. I have read about people that have this stack but they dont tap the pump. What does the comp do if its not tapped? Also can i run the smarty with timing, if i turn the comp off? Just trying to get an idea of the options i have with this stack and what would net the best all around gains.
