Thanks!
I found out on the flats that the dealer had reflashed my ecu (was Powerchipped), so I hit the stock limiter at 157 radar verified. Car was pulling HARD, and I was so disappointed. Top speed hit was 183 by a TT 350Z. More photos from the flats are here:

There was a WS6 transam that hit 159... those things are geared so weird with the super overdrive 6th gear. He redlined 5th @ 159 then couldn't maintain it after shifting into 6th. Pretty funny.
