Hey guys just put on a powerbomb header, Powercore IV 2, with a K&N precharger. Trying to decide if I need to do a stage 1 or a 2 on the rejetting. I don't plan on doing any more mods (unless some squid on a Raptor smokes me!).
I live at sea level and do half my riding here, the other out at Dumont Dunes (3300 Ft above sea level) Any ideas guys ?

PS...anyone have torgue specs on the header pipe ?
Thanks all......
