Boost gauge-positive or negative pressure?
Hey guys im pretty sure i did it wrong because BOOST means boost on the gauge right? anything + 0 ? and anything below -0 is vaccume ? well i put the gauge supply between # 2 & 3 runners on the intake and the gauge reads a negative when its running please

its more then likely correct, motor makes no boost till about 5000rpm and the gauge will read negative (vacuume) untill then.... had a chance to water test it yet and put that to test?

You should see around 5-6 pounds of vacuum at idle, then the boost will kick in around 6k rpm.
