Yes like Rich said, the main difference is the turbocharger and supercharger sections. Best to keep the models settings for those. The other items are relatively small changes , hard to know if they make any significant changes, I would ignore the mods that come withe sound set and keep the original model configuration. It'll be much easier to compare with other people flying the Sea Fury and if any updates are released, it will still be compatible.
I agree these sounds aren't perfect either, especially for the volume in cockpit, it's just a choice.
As for throttle settings vs sound and power response, that's another discussion entirely.
