Will I have to get a new tune or whatever computer ****? I'm not even sure what computer **** is on this bike now because I bought it this way.

 

You shouldn't have any problems going from one high flow a/c to another. They both have K&N filters. Your current tune(assuming it was tuned) should be fine.
