Default Running rich?

My sled has a problem of running rich ( mild blubbering ) up to 1/4 throttle. How can this be fixed? 2012 xf800 sp. it has done it from new but since I put on a mbrp muffler it seems worse.

I do pin it! But seriously is there a way to adjust? Has anybody remapped the stocker? Not a big deal just annoying at times.

Doesn't a fuel control unit only increase the time the fuel injector is open, not slow it down! I have one on my cruiser and it allows more fuel not less?? Can or is there no one that re mapped there factory one?

I'm curious as well. Have heard mention of it but not any specifics as to how or where.
