boost gauge problem?
hello, should my boost gauge read 0 when it's not hooked up? reason i ask is because, my bosst gauge reads 3 psi when the car isn't on.... even when it's unhooked... which would explain why i thought i was running 13 psi... so i got a new gauge, and this one reads a little vaccuum when its off or unhooked.... so now at WOT i read 9 psi..... so what is the deal? a bad batch of gauges? they are autometer and came from a local speed shop..... i'm getting another one tomorrow... my buddies autometer gague reads 0 when off.... what do you guys think?

well, alot of gauges don't read zero when off, not abnormal. Autometer has gotten a reputation of not being accurate. If you get another one... make sure all the fittings and nice and snug, tight even. Make sure you don't have a boost leak and then measure. Also, you connected the boost gauge to the nipple on the intake manifold, right?

yes i'm hooked to the nipple on the intake manifold... there is no boost leak there(at least i don't think so).. i used teflon tape to sure a good connection...i will look into hooking it up at the MAP sensor. i just don't get why one reads 13 psi and 9 on the other.
