I got a boost gauge and was wondering where I should hook up the vacuum line to pick up the boost reading?

 

I did mine between the manifold and boost pressure sensor.

 

Estimating that LINE will be very long from that point to inside the car, taping into that line won't degrade the reading to the BOOST sensor in anyway would it?

 

I wouldnt imagine so.

 

Nope. I have about 4 things T'd into it

 

i just got a boost gauge, and I have an extra nipple right below the bac valve, i used that. however if the pressure sensor is hooked up I get maybe 5psi, but the stock gauge reads full boost, If i cap off the pressure sensor house, my boost gauge reads a steady 6.5 psi all the through?? what could be causing that, should I just "t" it?

one wierd thing is that I already have a "t" from the pressure sensor and manifold with a little house going to the little nipple on the stock bov. Is that the right place for the hose??

one last thing, anyone happen to know what sort of vaccum I should be reading? its barely reading 10 on mine.

thanks

 

I t'd mine in between the blow off valve and ACV
