tune

Hey, I have a 2010 fz6r that has a one-piece stock exhaust system. Bike is bone stock, with no mods So I was thinking of having a workshop cut my exhaust straight after my o2 oxygen sensor, and have them weld a pipe and add a SC-Project Slip-On Exhaust at the end. Would I need to tune my bike...

So I upgraded to a new two brothers​ exhaust. Got a power Commander FC but my economy is gone to hell. I tried fiddling with the mapping myself but I'm not sure if I'm killing the bike. Does anyone know what the best way to map a touring model is? Or what I should be doing to better tune the bike?
