MW-50 sound happens even with MW-50 off.

[SMH]

The engine sound jumps up in pitch and volume as if MW-50 is on even when it's off.

Because Mw-50 injection alone will not change engine sound, the main factor is rpm then MP, And the throttle alone will allow you to got to higher rpm and higher boost w/o mw-50 system on.
