I dont know if I have just never noticed this before but when I shut my car off the boost gauge doesnt go all the way down, it stays right at 20-21 HG where it is at Idle. Is this normal? During normal driving the boost gauge works fine but it just stays at 20-21 when I shut the car off. Is there something I should look for that may be disconnected? Or just take it to the dealership and have them replace it?

 

no im pretty sure mine does the same thing.. i dont think theres nething worng with it ,, if its reading pretty accurate boost i wouldnt even worry .

 

mine used to sit at 0 after I got it, then out of no where it started doing the same thing yours does, no idea.

 

I guess I just havent noticed it before. Thanks guys!
