Default Help needed with my friends B5 RS4

Howdy folks been a long time. Need a little help. So i have come to the best place i know. My friend here in poland took his b5 rs4 into the shop and had the following mods done. New exhaust manifolds similar to MTM. KO4 turbos with a rs6 wheel they say wheel is 2mm larger. The stock exhaust had the precats and middle silencer removed. The car was then tuned on the dyno. There is a large debate raging over here about the hp the car made some say way to much some say way to little. What would you guys expect to see at the crank with these mods to an otherwise stock rs4? I will post the dyno graphs later i would just like to get some educated guesses to try and put and end to this never ending debate over here. Ambient temps on the graph were 11C. I promise to post the graphs but please throw out your expected numbers. AT THE CRANK PLEASE. Dont want the dyno graphs to taint the poll.

You're asking for power at the crank but said "the car was tuned on the dyno"?????

What boost level???

AWE shows 460hp at the crank with the K04's in their kit so you should be above that if you have a larger, more efficient compressor.

Boost was 1.6 bar and the dyno gave WHP and crank horsepower numbers.

My guess. 550-600.
If he is running the stock RS4 fuel injectors I would guess less.
