All fine with dyno.

Rev limiter are 6750rpm
Its normal what rolls up to 7200.

As i told, i change only turbo to K04 from 4c and remove cat.

If you didnt trust me - see video on top of the topic and see how i roll-on race with 378HP Audi S8

In attachment - comparing between stock graph on my friend Alfa 159 and my new config.

but with chip+exhaust+intake you can got more.

I just take one new turbo, rebuild it with new components and fit bigger compressor wheel.
Can sold for 650euro + delivery cost from Belarus
