Is this old news? I knew the rs4 was making less power than claimed but is this accurate?

This shows that the RS4 is making exactly what they claim, maybe even more....
Are you confusing wheel hp vs. engine hp? According to this dyno, if you back calculate engine hp from wheel hp, there is only a 21% driveline loss, which is low for the quattro system. Most dynos yield a 25-28% driveline loss. If you apply that figure to your wheel hp measurements, the car is making more than 420hp.
