I'm not familiar with the pc3 but for it to not even start I would think it has more to do with something else other than the tune. Over the years of experience with tuning cars/wheelers/skidoos they always seem to start, but may idle/run bad (unless the map is way the heck off). I'm sure someone will chime in and give you some help.
It's neither. We did have it running on a tune for a yosh slip on and no lid. It ran kinda ok with the lid on but the lid off it won't even start. Hes gonna put a fresh plug in as im pruty sure it's bad and i'm gonna get him a different map. See ya'll over on r/s in a few.
