Great responses everyone, that's the kind of back and forth discussion I like seeing!

At the end of the day, we strapped on the old VBox and grabbed some acceleration and braking numbers on the long flat straight and were impressed. Acceleration-wise, it's a testament to repeatability, overlaying almost exactly on our 2010 Performance-Package SHO with a 5.2-second blast to 60 mph and a 13.7-second quarter mile at 103.2 mph (0.2 mph faster than the last one). Braking, however, was a big improvement at 106 feet versus 112. There was no chance to get figure eight numbers, but you can expect lap times to drop and overall g level to rise with the improved braking
So the PP is 0.2 faster in a quarter mile.Z
If I read the article correctly, MT was comparing the 2013 SHO PP to their original test of a 2010 SHO PP:
"Acceleration-wise, it's a testament to repeatability, overlaying almost exactly on our
2010 Performance-Package SHO with a 5.2-second blast to 60 mph and a 13.7-second quarter mile at 103.2 mph (0.2 mph faster than the last one)."
So the 2013 SHO PP they tested was
.2 mph faster in the quarter (not .2 sec faster) than the 2010 PP. Mags rarely test the "base" version of a performance car, everyone I can find of the 2010-present SHO's are all PP.
