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

If you changed the gasket under the supercharger money is on the gasket. If injector were leaking you’d have a miss. Get a vacuum gauge and hook it to the intake. It should be steady 25 -30 inch. Less than that or fluctuating gauge means you have a leak and since it isn’t missing im betting its the gasket. Try spraying some carb cleaner around the gasket near the number 2 injector. If it’s gasket you’ll hear a slight change in rpm and the whistle will stop. Good luck.
