SCC Project 08 WRX makes big gains with Legacy K&N intak

There is a complete write-up on what they have done so far:
brakes, wheels & tires, coliovers, mirrors, chin spoiler, flat black paint and a K&N Legacy Intake that netted peak horsepower and torque gains of 27 wheel-hp and 32lb-ft. The article doesn't mention a tune, so i can only guess that it is untuned.

That's an insane gain from an untuned intake! The new head design (DAVCS etc.) have really allowed some impressive gains!

I can't wait to see what happens with reflashes.

I can't explain why the gains are so great, but I think you may have hit the nail on the head. From what I've read, the new ECU is very adaptive and very aggresive (there have been remarks that it runs very lean before 3,500 RPMs, close to 14:1 AFR) with a great deal of timing advance. Prior to the Dual AVCS only the intake valves were affected. my guess is now that both the intake and exhaust work together, you may well see some dramatic increases from pre combustion modifications.
