Apply the ppf with the ppf-o-matic onto the map it tells you to. Then FTP into you're Xbox and replace cache003.map in either X, Y, or Z. Note: make sure the map is decompressed before you patch it.
Also, makesure that your cache.003 map in you x,y, or z drive is bloodgulch by playing the lvl before you do anything, or just opening the cache map in an editor to see what the name is!
