Is it normal for the booster to make a loud air noise when letting off the pedal?
I will try bleeding tonight and can take some pictures if that helps

No its not normal to hear that. If the pedal is firm and you don't have to pump it. I think you have a bad booster. I see a lot of the aftermarket boosters bad right out of the box, even the USA made boosters.
