Hey Folks. I ride a 2005 HD FLSTCI. I just drilled out the exhaust baffles. Do I need to take this in to have the computer remapped? What exactly is a Stage 1?

 

If you have a stock air filter you dont need a new map. If you get a high flow air filter you will need a new map(with or without new exhaust). Stage 1 mostly is referred to as air filter and exhaust upgrade. however, a big bore kit without cams and head work is also a stage 1 upgrade.

 

Dude your avatar is obscene, I am sitting here with my daughter...[:@]

 

Here is a good reference for each stage and mods needed.
