best spot for boost gauge reading??

wheres the best place to hook up my boost gauges for accraute reading? i have mine hooked up to the pressure sensor as seen in this link, you notice the black vac line over the BOV, and it tees off to 2 red vac lines, the one going to the right is the pressure sensor

On the throttle body there are some good vac nipples. Im not sure if there are any free vac nipples on a fully stock engine. But mine has like 10 open nipples (removed everything from the motor).

Did you replace the vac pellet when you did this back top the pressure sender or ???

You know the restrictor pellet is needed for the stock pressure sender to read correctly and send the correct signal to the stock ECU.

Is the gauge tapped between the pellet and the intake, or did you put the pellet after "T" for the boost gauge?

On mine, I had to put the pellet after the boost gauge tap (on the boost sensor side of the tap), because my boost gauge had a delay in response when the pellet was between the intake and the tap.

It did when the car came from the factory...

It is located within an inch of the intake connection on the pressure sensor line.

it's needed for the stock pressure sensor to provide a buffered signal to the stock ECU.

The location we have been talking about is easy to get to and the factory uses it for the stock ECU and boost gauge... sounds like a perfect spot too me.
