I purchased my 08 renegade 800 used and when i got it, it came with a muzzy exhaust and a muzzy digitune tuner. Since I got the bike I have added snorkels on it. I was wondering how do I use the tuner and how I can get the best performance with it? Do i need to retune because of the snorkels? BTW the bike ran fine before the snorkels and it runs fine now with the snorkels.
