so i just got done installing all my gauges and greddy turbo kit on my 95 d15b7/d16z6 and it pulls 20psi vacuum no prob but give it throttle and no boost just slowly comes up to 0, checked couplers for leaks, nothing, possibly a faulty gauge?

 

Doubtful. Sounds like you've got a leak somewhere. Is this chipped and tuned? More info on the setup would help.

 

You might get more help in the forced induction section

 

are you doing this in neutral?

 

That would do it. The engine has to be under load to build boost.

 

nope took it down the road, setup is greddy tdoh4, chipped yes full tune not yet

 

Well you should be able to TELL if you're in boost and not rely on a gauge to tell you. Right now I'm still leaning toward a coupler or even the intercooler having an issue.
