They have the date wrong. It was just the last friday. Date on computer must be wrong. Measurement was at the wheels no special calculating involved for how much power at the flywheel.

I need to get the car some registration then I'll go to a dyno day and get another reading and I'll post that aswell

It's straight forward. You just need the turbo + manifold. You will have to cap off the s4 twinscroll selnoid. You will also need the gasket between the turbo and manifold. The others should work fine. Just so you know the coldside of the turbo is the same. Thus you can use the better of the 2 turbos you have. I used my old s4 turbo and just used the hotside of the turbo and manifold.
