Just wondering if I'm the only one that can hear the intake manifold vaccum when driving around. Seems a loud to me, but the dealership told me it was normal based on the composite intake vice an aluminum intake....

 

Yeah, with my three piece engine cover off, I can hear a noticeable "skrsh" noise when I move the pedal quickly. I wasn't sure if it was a vacuum noise, or the injectors spraying fuel quickly.
