Old pessima BOV

I have just noticed, i dont know when it was changed or if it was intetional but compared to other turbocharged cars the old pessima has no sounds for the turbo. I loaded up the track version of both the pessima and 200BX and the difference was quite noticable. I ran the game in safe mode and had cleared the cache before trying this aswell. While you can hear a faint sound it is nothing compared to how it was before. The stage 3 turbo has a noticable sound but it is only the turbo spooling. Im probably in the wrong here but help or someone telling me what is going would be appriciated.
