I spoke to the guys who build the Corvette racing engines (yes, Katech) and they said that all new Z06's make right about 505hp. Chassis dyno's are just not that accurate. Every engine Katech has put on an engine dyno made the correct hp. I don't believe the Audi is make 400 hp until it's put on an engine dyno.

That is exactly the point. Dyno numbers cannot be used to establish an absolute number. Depending on the dyno type, run condition, and calibration, you can easily blow up numbers.
Track number, on the other hand, doesn't lie.
109mph in a 1/4 with that much weight tells me it's making right around ~320whp, which is VERY impressive.
As a reference, a 350whp evo around 3200lbs traps 114-115mph.
