I have a aem boost gauge that reads 4lbs vacuum when the car is not running, does this mean I am 4 lbs off from the boost I am actually running? If so, is there a way to fix this?
Thanks

 

That sounds normal but when i had mine i read like 10 lbs vaccum

 

has anyone else seen anything like this with their boost gauges?

 

I have Autometer. reads 0, I'd call AEM. BTW thats inches of vacuum . Has it always read the same ?

 

yes it has already read 4 inches when the car isnt running, which seemed odd to me. I will try to get a hold of AEM, anyone else seen this before? i dont want to think im running 20lbs of boost when its relly 24 lbs.
