What cams?
It should not misfire with or without the correct fuel map.
No cam changes the timing or fuel requirements THAT much to cause a straight up misfire.
Will it run strong as it should? No, but it should fire on all cylinders - always.
Depending on the cam it could presently be running lean or rich but STILL... both cylinders will fire.
Timing may not be optimal but you are talking minor degrees and again it will still fire.
At idle, all timing and fuel requirements are near identical for every cam ever. If it's misfiring at idle you should check Cam timing and pushrod length as already mentioned.
