Mesh Resizing Issue

Haven't been able to locate a solution to this problem anywhere yet, so I thought I'd ask here in hopes of saving myself some time. I'm completely new to modding, and have been working on importing a new race into an existing mod. I successfully transferred my first capital ship into the vanilla game, as a test pretty much, however I realized it needed to be resized to better match the existing ship sizes. The problem comes when I use the Mesh Resizer Tool. It works perfect, and all the particle points (weapons, lights) are moved to their new locations on the larger mesh, except for the exhaust particles.  The new larger mesh file shows the exhaust coordinates in the proper location, however they are not properly aligned in the game. I can go into the exhaust particle file and manually redo the coordinates, but then the exhaust isn't enlarged like the rest of the new mesh. As I'm completely new to this, I'm sure there is something I'm failing to understand here. Why have the coordinates for the weapons and lights all lined up on the new larger mesh, and appear to have scaled themselves as well, but the exhaust has not? Is there a simple way to scale all the coordinates in a particle file at once? Once I've scaled the coordinates, how to I scale the particles up in size to match the new mesh size? I've played with the particle width and height values, in the exhaust file, but it doesn't seem to do anything. Any help would be greatly appreciated.
