It can be turned off in the tune and many owners and/or tuner shops turn off DFCO to make the pop stop. I happen to like the sounds so I'm good with it.

I had DFCO on on my H/C/I '02 Camaro and very rarely ever had pops coming from my exhaust. It's on from the factory. It cuts fuel so you shouldn't get pops. If you turn it off yeah it will pop more but IMHO that fits in with my bad tune theory because it shouldn't be turned off. It wastes fuel and kills engine breaking
