LMS already had my strategy code so I didn't need to pull it when I got the MyCal so I am no help with that.
Regarding the dying duck sound: It makes the noise whether you have the BOVs vented to atmosphere or left hooked up to the recirc tube. I tried it both ways and the noise was the same either way. Anthony said it was due to higher boost but I am not so sure since we get it more after a low boost situation than high boost. It does, however, seem to be related to a release of boost - however slight. Maybe it is a result of boost at a lower RPM than the earlier tunes???
