Yellojacket,
On my RR I'm running DJ124's for mains and DNO129 needles on the 4th slot from the top.
I'm running a full V&H pipe and a K&N filter and I've opened up the airbox. I also live at 2000 ft, so that won't help you much. I would go with the stage 1 and run the 118's and the needles in the center slot to start. Play with it until it feels right and then take it to a dyno. That will tell where you have to go from there.

Have fun.


Mike
