i just put on a fmic and i lost 10 pounds of vacumme and 10 pounds of boost helppppp please
 
I thought so this might sound dumb but I re tighten every thing and sprayed it with carb cleaner but imma reinstall it I think it's weird cuz car runs great an hold strong at 5psi which I don't get 0.0
 
After all the testing found the T fitting I used for the boost gauge ,bov and intake manifold had a brass fitting restricting flow replaced it boost is back Nd so is vacuum
