    Vac leak?

    My car is sitting at 15 at idle warmed up is this normal? Also I am boosting 20-21lbs with a GIAC chip is that normal? My friend told me i shouldnt be concerned that my car is sitting at 15... Just looking for some opinions.

    That doesn't sound right. You should be at 20-22 inches of vacuum at idle. I don't have a GIAC chip so I don't know for sure but it sounds like you are boosting high. I would pressure test.

    Yup.

    If you just have a boost guage, you should be idling at 0
    If you have a vaccuum/boost guage, you should be idling somewhere between -22-26Hg.

    It could just mean that something is wrong with your guage...
