Interesting article regarding the LS2, 472BHP with race headers on an engine dyno. Only 400BHP in the vechicle, I suspect the air intake to be big factor in the difference, in my logs i'm seeing 92-93kPa @ 6400rpm at WOT when BARO = 102kPa.
I note from the article 29 degrees of advance dialed in with ported heads and fast intake.

"As you can see, the AFR heads and FAST intake really helped the LS2 inhale. With a gain of 41 hp and an increase in torque of 39 lb-ft, only the limitations of the stock cam were holding back the engine. Still, for such a mild cam, 503 hp and 489 lb-ft of torque isn't too shabby. Timing was set at 29 degrees"
