    I recently put my 3.4 pully on and it sometimes squeaks on start up? This normal? The squeak goes away but I was just wondering.

    I also have zzp downpipe w/cat into 2.5in no res and 2 magnaflow mufflers. And a KN&N cai. Thing im getting next is the overkill pcm, which I hope will make a difference. First Post so Hi.

    could it just be your belt squeaking?

    Sounds like the belt squeaking to me. Make sure it's on right to begin with.

    it could be the alignment of the pulley you just put on.

    did you put a new belt on the car when you changed the pulley? Probably not, doesn't have to be smaller but it does have to not be worn out...

    How long does it squeak for? And are you sure it is the S/C or around that area that is squeaking?
