My buddy blew a ring and is putting a 474 big bore kit in his '08 ltr450.

will he need to purchase a tuner? like a pc3 or a pc5. I had one on my sportbike awhile ago and all i had was a full system on that.

i was explaining that he will most likely need to remap the fuel. I thin khe probaly blew the ring because he was too lean anyway.

Too lean, if he had stuff done to it without a fuel controler of some kind more than likely. Yes, go ahead and get a PC.
