Is there enough control range in the ECU's wastegate control to work the Wastegate until the requested boost is reached, or is the control open loop? Certainly, spool up would be slower, but the K04s would be stressed much less and would outlast the K03s.
What would happen if this were done on a chipped car?
Of course, to benefit from the full potential of the K04s, all the other trimmings are desirable, but would the engine protest without them?

not sure - seems like fuel would be an issue - running rich or not? it seems
like your always fighting to keep the car running right - then again - i spent the day trying to locate a boost leak
