Hey try this mod,

https://www.gta5-mods.com/misc/gameconfig-for-patch-1-0-757-2-update-at-each-r-update

Hey Everyone,

Kinda have a weird issue here... Any mods in the update folder won't work, weather its a replacement vehicle or an addon. The issue is happening in both the standard update folder and the mods\update folder... the really weird thing is that the x64e.rpf in the mods folder works perfectly fine as well as the update.rpf, I'm really stumped, I've even tried install mods onto a clean install of the game still with no luck... hoping someone can help me out! Thanks!
