Here's is the map that Dyno Tune offers for the Raider w/ V&H 2-1 pipes.... the values are adjustable, but I don't know which direction to take the numbers....
First, this is the fuel map. I don't mess with the fuel map since you can get rich or lean really really fast. Your better off messing with the AFR changing by a .1 and trying out.
second, if this is the map they are providing for your set up why do you want to change it?
If you have a BAK, I can understand changing it...so what I would do is download some maps that were made with a BAK and those pipes. Then try them out and pick the one that gives you the feel (power, acceleration) and sound (idle, and popping) that you want.
