550cc injectors is the common upgrade with the 1uz afm housing upgrade.

the housing allows more air to enter the engine, basically unmetered, because the housing is larger. if you didnt do injectors, you would run lean at WOT. there are several threads on here if you search "lexus afm and 550's".

and yes, power is the gain. how much depends on how much you put in. just the afm and 550's, a little.

add a piggyback controller and wideband o2, the power potential increases.
