Makes way more sense why the car sounds like this if its running on 3 cylinders. Hopefully that can help anyone who encounters the dreadful subbie sound

Glad to see you got that fixed. I didn't think the IAT would cause a misfire sound. I would pull the fmic and check it for leaks and the same for the rest of the charge piping as well.

If your having trouble with your couplers a little trick is to spray a bit of hairspray on the inside of the couplet and then reinstall. It Will not pop back off or if it does then you sir have just made a great deal of power. (Or your engine mounts are not sturdy enough showing to much movement)
