ok my turbo is install.i test drove it .but i notice the gauge only read vac,i dint see it read boost.so my question is at what rpm's does the gauge start reading boost? i connected it to the nipple for the cruise control on back of the intake manifold. my car is a 98 civic,00 b16a2,and drag turbo kit 57 trim.

 

Should see some positive pressure at least by 3500 rpm's full boost at around 5K!

 

uppppppppppppppppppp!!

 

Yep thats what mine does. I would check for leaks in the intercooler piping and vacuum lines if its still a problem

 

yea i'm guessin you have a leak somewhere......
