Oh OK. I don't use CSM so I'm not very familiar with how it does things, but I'm pretty sure it keeps a lot of its 'stuff' in the GPSaves folder.
Have you done a search for generic.txt (or failing that, have you tried doing a content search for one of the driver names in the mod)? That might turn it up, but be careful with a content search, as the driver names will appear in several places (such as the GPaedia etc). Basically, you're probably looking for a file laid out like this:
** gp3edit - performance file **
