First, I hope this is the right section. Next the problem. Ever since going stage 2 I get this high pitch wine, which I cannot replicate, going about half throttle or high boost, anywhere from 12-19lbs. This happens only in gears 3-5. It's louder than the normal intake whistle. It's very high pitch. So I logged to see if maybe my car was running bad, nope log looks great. I tried to get a sound clip but I couldn't. Again this only happened after my catted downpipe install. Could it be I'm just hearing my turbo more now that I have the better airflow? I looked for rips in my intake, looks ok, dirty but fine. I'm losing my mind. It's probably the most annoying sound I've ever heard. Help plz! And if this is in the wrong section. Plz move. Thanks again!
