A stock SS maro runs 13.7's 13.8's 13.19's sam e as TA WS6 and Z28 only diff between all of them is stock exhaust and air lids and lil shit like that its a 13 sec car. A cavlier can run that easy with enough spray. I just dont belive he did that all stock with just a turbo running a shit load of boost on stock everything.
