F15 and F5 much louder than other jets

[M0ltar]

I need some help. I have a mod pack that I have compiled. All the sounds are the sounds that I want, but the 2 planes mentioned above are astronomically louder when in burner than anything else. The Su27 for example is perfect audio wise. The F15 and F5 when in burner break eardrums when in the cockpit internally.

 

Can anyone help me figure out why? Ive changed some .sdef variables on gain etc but that does not seem to be changing the volume.

 

Below is a link to the mods pack that I am using. Again, the volume issue seems to be only with the F15 and F5 because, at least what I assume, they share sounds.
