So how do they (I'm assuming lifters) sound for you guys (with windows up you can hear better).
Just want to make sure I'm good before I put on the intake and tune it.

I posed the question about the noise to one of the Chevy engine designers because I noticed it on my 2012 and also on Corvettes. He confirmed that it is the direct injection. Lots of pressure there
