I'm probably looking in the wrong place, and it seems like the kind of thing y'all could point me in the right direction with. Working on a 2013 Camaro SS that's been pretty heavily modified (like, no way it will start, let alone run, on a stock tune: intercooled Vortech setup with 800 lb injectors, ZL1 fuel pump, heads, headers, cam...fun toy!) Owner has taken it in to dealerships a couple of times, and no matter what he tells the desk guy they always seem to flash a factory tune back on the ECM.

I'm trying to run down a locking OBD2 port cover for him, but all I'm coming across are ones for either Ford, or just plugs that don't lock. Anyone know where I can get one? I assume if ones are listed as specifically for Ford/Dodge it's because there's a housing clearance issue or something with the dash, since the port itself is universal.

Edit: I'm the only one who has turned wrenches on the car for him since the day he bought it, the only reason it ended up in a dealership is because it needed the front end aligned, which is not something I'm set up to do (because I suck at them, so people are better off getting someone who won't take twice as long to get half as good a result). I don't have the first damn clue why they'd have been anywhere near the OBD2 for an alignment, I'm guessing some tech was fucking around with it because they were curious what he had going on there.
