i dont think its a problem of your vacuum source, its more on you wiring power to your gauge or prolly its defective

I actually went to autozone and bought a very cheap mechanical boost gauge 24 bucks, that should do until my new gauges get ordered . I will be doing the install on sunday. Im scared to death of not running the car with a boost gauge. I have a greddy ultimate and its tuned at 7.5 psi from the previous owner but who knows, im not going to risk it

^^Kenny said they had to bring in a friend to solder the board around. Don't remember everything exactly, as it's a good 2+ years old mod I had done.

Yeah, the connector coming out of the boost gauge that plugs into the controller. Little white connector. If you can get the color of the wires and what order they attach into the connector, that would be great.

NP i will have that pic up when I get home from work.
Also as i stated before, i bought one of those mechanical boost gauges at autozone. Are these good enough to tell boost pressure(just needed a boost gauge until my new ones ship)

Why not just stay out of boost until then. You can hear a turbo spooling.

Sweet, thanks for the pic. As for tapping the boost gauge, there is really no one particular place better than another. Just make sure your vac source has no leaks and your good to go. Vac lines coming off the throttle body are a great source.
