OK hear is my question. Right now I am running the stock size jeting with a K&M filter and the Proflow flange. Im around 1000ft where I live and going to be taking a trip to Moab, UT next year to around 6000ft or so. What size is the stock jeting and what size should I go down, oh and brand. I herd that brand matter, sizes are not the same brand to brand. Should I move two sizes or just one, or more? Any help is appreciated.
