18 mm/hg of vaccuum is normal. At idle, I am around 22 mm/hg.

Integras don't have EGR.

Do you understand what I am saying when I say that the Map sensor wire needs to be cut, not spliced, with one wire on the blue box going to the Map sensor end and one going to the ECU end? The two wires should never touch.

The bypass should take the place of the steel coolant hose running from underneath the throttle body to the head. There is another thing connected to it that runs from the valve cover to the stock intake arm. The steel thing needs to be removed and the bypass hose should be run from underneath the throttle body to the head and another hose should be run from the valve cover to the nipple on the intake pipe that Greddy provides.

I wish I could be there and help you out because I know what is wrong, it is just hard to explain it to you.

Good luck, I hope this helps.
