don't go buying anything yet!! Talk to someone at AEM, I had a problem with my autometer, thought it was my guage, sent it in and they sent me a brand new one for FREE past the warrenty period and turns out the rubber plug for the hose was worn out causing me to have a leak. Good companies want to keep your business they will do what ever they can to help you!

 

i went for a little cruise tonight. stopped at my dads then came back home. the gauge worked perfectly fine this time round. im confused...guess ill wait and see what happens in the near future. thanks again for the replies

I have a similar problem with the autozero function of the AEM boost gauge. If I turn the car to the accessory position and wait for the gauge to autozero before starting the car it works fine, but if I don't wait it will read 0psi when it should be reading vacuum at idle. I tried a couple different circuits but none seem to work right.

 

^ yup im noticing that exact same problem! maybe thats just how they are supposed to operate. kinda lame
