No Mods, Do I need custom tunes?

[LTMARK]

Hello, I purchased my gryphon used I rarely ever use anything other than 93 octane. I preformed the Gotts mod and bought a K&N drop in. I have tried different settings but usually leave it on the 93 performance tune. Other than that I have done no performance modifications. I was wondering if I should send in my gryphon for custom tuning, maybe a 93 towing? I am not sure if its worth it. Is there more to custom tuning than I am aware of? On my motorcycle I have a power comander, exhaust, and air cleaner installed, so the bike spent some time on a dyno getting dialed in. Is the custom tune the same way or is it just another generic file? Thanks
