My car has been leaking boost for some time now i thought i was my old a-piller boost gauge just had a weak seal but today i got rid of that entire gauge setup and installed new gauges with new tubing and once i get around 17psi the boost gauge needle starts bouncing between 15 and 18 and it sounds like a can of compressed air is being sprayed from the drivers side of the car.
anyone have any ideas?
Im thinking maybe a leak in one of the IC connections.
Also i did a search but could really find anything helpful.

Please any input would be greatly appreciated.
has this happened to anyone else?

Thanks,
-Bryan

I let everyone know what was going on.
Also any other ideas...Keep them comin

 

Well if you suspect an ic coupling, before you do your leak test go through all of the clamps and tighten them down and see what happens.
