So far a lot of the talk has been that one of the reasons the SVR sounds so good is the engine was remapped to dump a little extra fuel in when you let off the gas to create the popping and backfiring. So my question is, for those that have upgraded their ECU's/Pulley, did the exhaust sound change at all? Any more backfiring or popping?

No, the tune and pulley did not change the exhaust note.
