I found this out tonight when I was pulled over for a DL and ins. check point. Guy stuck a sniffer in my trucks pipe and then asked if I had a tuner. I told him NO and he walked up and jacked in to my truck to see. I told him he could not do that and he said they take my DL on the spot and impound the truck. So I called my cuss (he's a state attorney) and he said then can do it because driving on government funded roads is a privilege and they have the right to take your rights to dive on them away any time.
