First off... Welcome aboard.... Take a moment and post an intro in the NEW MEMBERS SECTION at your earliest....

The short answer is YES, you need the upload..... If it was just the mufflers, you could have left it alone....
&nbsp\\;
Once you installed the AC unit, you are now bringing in more air than the stock map was designed for... Therefore you need a bit more fuel to compensate for that extra air...
&nbsp\\;
You can listen to other riders/bikers/posers/virtual techs, etc.... cold hard fact is that you are running with an ECM program that was designed for certain components (Stock AC, Stock mufflers, etc...)... But more air without the additional fuel will generate higher than expected head temps, leaner combustion effect, and increased potential to burn up your pistons/valves....

Your call...
