But the dyno shows only 178Hp and 128Nm ... :(
You advise me why I have so little power whith turbo?
Thank you..

Does seem low, I tried to put in your compression ratio and turbo pressure into the garret app I used but it is not working, would give a bhp out.......... Leaks anywhere? Boost gauge working correctly? When is boost starting to build? Is rolling road you used calibrated?

My bike has standard compression so power will be higher at 4.5psi. Would have expected 3psi to be around 190-200bhp ish.

First dabble with turbos so I don't know!!!!!!!!!!!!!!!
