I just recently purchased an eBay special short ram intake... installed it no problems. However, I've noticed that pretty much in any gear when I step on the gas, it makes kind of a very faint whistling/whining sound. I haven't felt any loss in power, and the intake still has the loud air sucking sound, but there's also this whistling sound in the background. At first I thought it may be leaking air somewhere in the system, but I double checked all the connections and everything is tight. It also doesn't make any leaking sounds at idle or when revving in neutral... is this sound common?
