should have had an efi engine in it. Thats usually the sound of the wastegate shutting i think as someone mentioned on this site sometime ago. You dont get the sound in ERSTs because something to do with the metering unit i think. I think thats what it is

the chatter sound is from the compressor wheel stalling as the air is forced back through it when you lift off ( it has nowhere else to go with no dump valve ) . you can hear this noise coming from the induction kit. as far as i know you shouldn't get it on an mfi car as the flap inside the metering unit will close when you lift off,
