I'm scheduled to have my bike dynoed friday afternoon, dropping it off tomorrow and I have a question.

I'm planning on getting 39" baffled cholos to replace my 33" longtails, same head pipe and I assume same baffles.

Basically same everything except for length.

Wondering how much of a difference the 39"s will make vs the 33"s in my tune and if you think auto basic on the power vision will be able to correct it if needed. I'd wait but they are doing mine and my brothers same day and only time I was able to get in with out having someone hold my bike for a week. I can't get the cholos till next week so I don't want to reschedule.

thanks

 

I'm guessing it won't make a difference at all. You can ask your tuner though, he probably knows more than I do. Sounds like its a moot point anyway since you don't have the longer pipes and can't reschedule the dyno, so it's gonna be what it's gonna be!
