Getting 4* of KR with 7* already pulled...
Last year at this time when i first sprayed it with this tune and the same type plug (TR6) it had 0 knock, but i had 9* pulled out then and not 7*. Where should i go from here?
TR7 plugs, if so what gap and how much timing should i pull?
Keep the TR6's and go back to 9*?
