Well, I just got done with installing the lsx 70mm intake, Install was no thing, it went pretty uneventful, yet I noticed that my vac guage now reads 10hg in instead of the usual twenty some, and it is slow to go up, Have not driven it yet, because penndot, PA's dumb *** road department chipped and oiled my road, it this normal, or do I have a leak some where, tried to listen under the hood, but the headers make some loud noise when car is running. Any Ideas guys?

 

anyone?
