I have just installed an autometer boost gauge. When I turn the car on it goes to -20 like I was told it should, but I can only boost to 5-6 psi now. The car feels fine, there is no smoke and pulls fine too. Does it take time for the gauge to calibrate? I boosted about 2-3 times. Can that be safety boost, cuz shouldn't it be 7psi then. Or can it just be a leak somewhere?ECU shows no error codes.
