How is that possible?  And why? It seems they have lost the cool "whistling" at idle.

 

Anyway to fix this and get the old sounds installed?

Thanks

Are you sure its ProtoSounds-3?  According to MTH the last run of SD90MAC was in 2010 and were ProtoSounds-2.  Maybe your ProtoSounds-3 engine is a SD70ACe, which would sound different from a SD90MAC.
