i tore a lq9 down and the "factory cam" was 2 degrees retarded from the factory.so that would definitely explain alot,as to why 2 of the same cars would run differently.

now that i can be more specific (i guess)
i knew there would be a few that would be dumb founded or floored by the question because they prolly spent a bunch of coins and went just over 300 RWHP by a small margin
i put my truck on the dyno, i was showed "SAE" level. the tuner told me that to him "SAE"was what meant the most to him, as far as HP levels are concerned, as a tuner.
my truck put down 255-298 to the rear with a "tune only".
3.73s 275/45/20s new plugsTR55s ,msd wires, a "WIX" paper filter and a new wix fuel filter.
A/F at 13.3-13.6.
at 12.4-12.6 it did 260-281 but was detonating at 5200 on up.
my next option of making some more power was doing "electric fan" and "cat-back"
i dont see why 300Hp could not be achieved.
i just thought it was a legit question and a achievable goal.
GM has always lied about their the HP from the factory.
thanks

I made 270whp/290tq with just intake and blowmaster muffler on a 07 5.3l. With no tune and it was a hot August Texas day. Lookin to maybe hit 300whp with the 93oct tune and a iced down intake manifold.
