Specs say the SIII SC engine is at 260hp. What changed from S2?

The L32 is a supercharged Series III. Introduced in 2004, the main differences between the L67 and the L32 is the L32'* electronic throttle control, slightly improved cylinder head design, and updated Eaton supercharger, the Generation 5 M90. HP output is up to 260 hp in the Grand Prix GTP, though an inferior fuel supply system, and excessive torque management in the PCM, results in the 2004+ being no faster than the 1997-2003 Grand Prix GTP in stock form.

While I added the Gen V at the same time as the cam. Sitting on the engine stand..there was a serious difference in air coming out the injector holes (none installed) when I turned the pulley by hand on both.

The Gen V is a serious air mover.
