I’m not talking about a dump valve, I’m talking about an ALS as I’ve mentioned. This is where the engine timing is delayed which results in some combustion to happen in the exhaust (hence literal pops). This is used to keep the turbo spooled by MAINTAINING pressure across the system. It’s a performance system.
If your dump valve is popping I think there’s something wrong!
