You probably won’t like the answer but the Game Pass version isn’t really mod friendly. It runs through the Microsoft Store setup which locks down a lot of the files, so things like ScriptHook and police mods usually don’t work properly or at all. From what I’ve seen, people who want to run LSPDFR or ELS end up getting the Steam or Rockstar version instead since those let you drop files in and use mods without fighting the system. If you still want to try, you can mess around with permissions and mod folders, but it’s hit or miss and breaks easily after updates. Honestly way less headache just using a non Game Pass copy if mods are your goal.

I’d start by assuming it’s some weird interaction between ASC and the latest updates, not your setup breaking. I had similar micro stutters after a GTA update and it ended up being script load timing. Stage 3 probably triggers more stuff at once so you feel it there. What helped me was reinstalling ELS and the ASC plugin clean, plus clearing any old config files so it rebuilds fresh. Also make sure ScriptHookV and any related plugins are up to date because those tend to break quietly after updates. If that doesn’t change anything, try running without a few other plugins for a test. Sometimes it’s a conflict and not obvious. I wouldn’t stress too much yet, sounds more like a mod compatibility hiccup than anything serious.

From what I’ve heard, Jersey City PD mostly uses Federal Signal setups on their newer vehicles, usually the Pathfinder or SmartSiren paired with the standard Q2B style tones. A lot of departments around that area run very similar siren packages, so unless someone has a fleet sheet, it can be hard to pin down the exact model.

In my experience, even LSPDFR on GTA V is tricky on Mac unless you’re on Intel with Boot Camp. On M4 you’re basically stuck with cloud gaming or a Windows PC if you want mods like that to work properly.
