This is probably a stupid question. OK, 2002 Eglide, wild pigs slip-ons, big sucker, pc3r. Now when you go to powercomander website to get a map. Do I select stock ecm or stage 1 ecm for my map. Isnt it going to be a stage1 when its all said and done? Or is stage one ecm meaning 1550 motor. Im a little confused, please set the record for me.
