I've done the search of past questins but could find it. I have an 03 Raptor with Powerbomb Header with GYTR carbon fiber silencer, K&N, Big Gun Rev box, and air box lid off. With all of this what should I have for jets at sea level and also what should I run for what ever St. Anthony's sand dunes elevation is at?

the rev box is what I'm most curious about.

 

we can only get you close. I would try a 160/165 to start with and go from there, I am jeting my quad now and let me tell you you wont find the right jets by asking on these fourms. I have asked for a mounth and finaly jetted my quad and it was way lean.
