Air leak
Change supercharger over the weekend got everything back together now there is a whistling noise coming from the second Injector on the passenger side I can spray around the injector and the noise will stop can’t figure out if it’s coming from the gasket under the supercharger Or the injector it self changed the injector o ring and it’s still doing it any thoughts or suggestions

Yes its your gasket slipping or its a hose that is not tight or has slipped off. A Star Diagnostic scan will also tell you the engine condition. I’d be willing to bet that its your gasket and your number 2 injector is lean. Has nothing to do with the O ring. That just seals the injector.

Thanks for your reply it was the air line that runs under the SC I got it caught between the SC and the gasket once I got it out the leak is gone took the air line off the old SC it’s all good now
