So, I was trying to add in a Stage 1 Long Block for the pickup i6, but when i pasted it over from the truck's v8 code and changed the names, there is now no option for "intake" in the engine mods list in-game. I have no idea how this could be, Idk if it could be a variable issue, but I'm going to upload my file. I appriciate if any of you can let me know what my issue is.
