Is this a possibility with the autometer pro comp series boost gauge?

Im asing because I notice that sometimes at ZERO and even sometimes under heavy throttle at low vacuum I hear a small PSH form the BOV

so is the gauge reading wrong or is this normal

 

if your turbo is only spining a bit but not enough to boost (fill) a 1.6l engine with positive pressure it still could fill the charge pipe and let a little blow off out. I can rev mine from a idle and blow off but I cant rev it and make boost. I know I suck at expaning :P

 

i believe that's normal, mine does the same thing

 

Ya but I dont think his ever boosts, I think thats why he's asking

 

it's ok as long as it's not too loose to leak under full boost

 

mine blows off if i give it 1/32th throttle for 1/2 a second

 

thats noraml
call will blow off even if it reads 0 vac.

 

Yeah, that's normal..........mine does that too.
