OK, so I installed the Skunk2 Intake Manifold on my GSR, and at a certain throttle position, I hear a whistling sound. It's not horible, but I'm a perfectionist and this is going to drive me insane if it's not normal. Did I install something wrong? Or is this just one of those by-products of upgrading?

 

Vacum leak?

 

thats due to the additional air coming in through the manifold. perfectly normal

 

get some bigger than stock cams. Then at those certain rpm's you wont hear anything but a loud engine

 

sounds normal but you may wanna raise your vtec up alittle higher to about 5500.
