Wierd Issue - During/After Dyno

Well while I was getting my neo tuned it started making this suction noise over 5500 rpm's like it was a vacum leak from hell. And it was LOUD. I asked what it was and they said nothing. But now off the dyno driving around I can here it over the wind even. Just a LOUD ssssSSSSSSSSSSSS sound only when gettin on it though. But It was never doing that before, I dont think.

Any suggestions

Or maybe you have xs headers and theres some resonance that you never noticed outside of your car

Could be your thermospacer. When I removed my Thermoblok, it looked like it wasn't fully sealed. I was getting a whistling noise that I didn't care for.
