I recently put the stage 2 slp kit on my 2010 m8, and with the pcv hooked up it will not start, if i unplug the pcv it starts 2 pulls like it has since it come out of a crate. I have tried screwing around with the fuel at 250-1250 which should be start up and it doesnt help when it sits outside and gets cold. It just will not start when its cold out till you unplug the box. any help would be greatly appreciated as im reve bound on tuesday
