Default QUICK help needed

Long story short....my Nightster got bumped off phase 1 so I found a killer deal on 2007. Im picking it up tomorrow. I have V&H short shots waiting to go on it. The bike is stock right now....do I NEED to tweak the stock map if I'm only running the new pipes? Im ordering the Power Commander and a new air filter this week...I just happened on this bike so I don't have all of it yet but I still want to throw my pipes on. The bike is already broken in and just had the 1k service done.

Thanks.

These are actually full pipes. But leaving the stock A/C on, I'm hoping they aren't going to flow enough to lean the engine out.

Full V&H Short Shots pipes on a 2007 could be a problem because of the EFI. The injection system's oxygen sensor is in the exhaust pipe not too far from the cylinder (front, I believe)...

There are two O2 sensors, one on each header pipe.

I stand corrected!

Personally, I'm not a fan of liquid-cooled enginesor EFI.
