It's 12:00 midnight here in N.H., I'll throw the light on it tomorrow and get exact numbers.. But I think if I remember correctly it's at 15* and 32* total. I'll get back about this tomorrow.
Thanks
Ok, the way I just set it it is at 9* with the vacuum disconnected and at 17* with the vacuum connected. It pulls hard and I don't hear any pinging but I haven't had it on the highway yet..
