Intake backfire ???

I'm actually getting a backfire in my intake, not the exhuast

When a blip the throttle with little load on the engine it will backfire in the intake once or twice before it revs up. Any does it if the engine is running less then 2K rpms. Sometimes its light, sometimes it sounds like i blew off some pipping

It did do it alittle before the blower was installed, so i'm almost certain its not from that. Still running stock MAF, no DTC codes...

Add fuel or add ignition advance or both. This was very common before MSD.
