Does anyone know the vacuum pressure we should have at any place in the system? Since there are about 5 vacuum hoses coming from the TB and dynamic chamber, we should have 5 different pressure values, right? ???



Thanks for all informations you could give. https://www.nopistons.com/forums/pub...>/rolleyes.gif

The stock computer gets its reading from the pressure sensor. So thh nipple that the pressure sensor gets its reading from would be your best bet. Otherwise just try to choose a spot after the throttle body that gets a reading from all ports.

Thanks for trying to help Ace, I really appreciate it!

But what I meant to say is that I want to read the vacuum pressure by inserting a tee fitting and read the pressure where each hose is connected to the TB in order to find out if one of them is not receiving enough vacuum. But since each TB vacuum output has probably its own vacuum pressure, I need to know what vacuum pressure I should be reading at each output. Are they supposed to give all the same vacuum readings? I'm not sure about that. ??? So far I haven't found anything about this on the web.
