When the engine was certified at 426Hp, it was with all pulleys attached. When the power steering pulley is disconnected, and replaced with an electric pump, the load is decreased. When the load on the engine is decreased, the certified Hp will in fact increase. The LS3 without all belts and pulleys, actually produces around 480 Hp.
The amount isn't all that great, but there is an increase of power.
