You will need an immobiliser, eastern states cars aren't required to have one, so chances are you don't have one in there yet. So go get one.
If the car is low, it shouldn't be too big of a deal, mine only has 15cm of clearance at the tip of the front bumber and they passed mine without any issues.
Make sure all of your wipers, lights, safety equipment works.
To save you some hassle, just unplug your turbo timer or set it top not have a countdown.
Hide your boost controller away if possible, it shouldn't be a problem, but best to play it safe.
