Settings for 2011 Renegade 800xxc

[darkstar]

Can anyone reccomend setting for a full system exhaust for a 2011 renegade 800 xxc with penland pro muffler .
I had to use my optimizer off my 2010 Outlander and wondered if any settings could be tweaked alittle bit .
I plan on opening up the air box today with 4-5 one inch holes .
The stock bike seems really rich and lugs a bit .
Thanks

Its likely lean. All the 09 up 800 R engines run lean. Start with 4 / 5 / 4 / 4 / 4 and fine tune from there.
