Jetting and elevation change

I'll be heading from Medford (1,300ft) to coos bay(sea level) for dunefest later this month any ideas on jetting for sea level? I went a few months ago with my bike completely stock and was lean, bike ran real hot and was getting some pinging from time to time and less than normal power. Since I've added a k&n with clamp adapter kit, ditched the airbox lid and added a full dg krome power exhaust. I've got jetting dialed in at home 45 pilot and dynojet 148 main. My jet kit came with a 150 also, I know DJ and mikuni numbers differ, should I bump up 1 more size so 3 over stock or leave as is?
