Default SE Heavy Breather vs SE A/C (need remap again?)

Hey fellas,

I've tried doing a search, but everything I found on the HB doesn't really answer my question...

I currently have the SE A/C with the HD download. I'm thinking of getting the Heavy Breather, but am wondering if I would need to re-map if i swapped them out for each other.

I asked my dealer, who's a buddy of mine, and he said they can just swap them and I won't have to do anything else. He said the difference in air flow isn't much. I kind of believe him because if he wanted to sell me on another download, he could have said yes and having to do it again.

I want to get your opinions on it as well. What are your thoughts?

Any help is greatly appreciated!

Thanks!

My dad and I were told the same thing in WI when we went to the 105, but we haven't bought one yet for his Softtail.

no, although it will flow more air technically, unless you have done headwork or cams etc, the engine wont suck any more in then needed.. the se ac already breathes great, and no remap is needed at all.. i had a se ac for 5000 miles before i switched to my heavy breather.. no change was needed for me..
