The OEM K24's spool better than the K16G setup but the A3076 and A28 setups all spool similarly although there is a much better top end and torque boost with the latter two mentioned. Although the torque drops off the horsepower is remarkably flat from about 4500 rpm to 7000 rpm except on the A3076.
The K16g's ultimately offer more mid-range and top end punch than the OEM K24's although if one wants similar spool to the K24 but with much more top end than what the K16G offers clearly there are better options. Graphs below.
In order as seen on the graph:
-K16G, 22psi, MS109, Markski Tuned
-A28, 24psi, MS109, Markski Tuned
-A3076, 28psi, E85, Tony@EPL tuned
-OEM K24, 15psi, 93oct, FVD Tuned
