it just T's into a vacuum line, closest to the turbo is best.

 

From the intake manifold is best.

please explain why you say that??? it really makes no differance, closer to the turbo is just more accurate.

 

k thanks guys

 

The pressure drops as it goes through the intercooler. You take the reading from the intake mani because it shows the pressure right before it enters the engine. If you take it at the turbo and it reads 8psi, pressure drops to say 7psi after the intercooler. Your gauge is reading 8psi when only 7psi is entering the engine. If the gauge also read vacuum which most do, it would also give a false reading of vacuum. Now explain your reasoning.
