Will Micron exhaust need PC3?

[sparkles254]

I bought my 04 636 about a month ago from a guy who already had the full Micron High mount exhaust on it. I was just wondering if I need to get a Pc3, because I'm not sure of how much that exhaust changes the fuel air ratio?

HHHMMMM ...Cant remember now if its carbed or injected...If carbed get it rejetted if not andf its injected get a pc3 and have it mapped for yer bike specifically...Online maps are a good start but are only a temp set up..

it's fuel injected and will need a PC3. Craig is right, a custom dyno tune is the best way to maxamize performance, but running a preset map won't hurt anything.
