The 2012 gt has 412hp and 2013 gt has 420. Boss has 444. That's 24hp. So I wouldn't expect a tons more. But from what I have seen online it tends to consistently trap a few mph faster.

But there are many differences in the engine (heads, pistons, crankshaft, intake manifold, compression) and rest of the car
