This is ruining my driving experience with my 930 Turbo !

My car has right around 47k miles and is regularly maintained.

In a nutshell, car runs great and pulls like a freight train,..........however whenever I am negotiating an extended hard left turn undermedium to high revs while in boost (when I Autocross),.....the carbillows heavy blue exhaust smoke. I mean a lot of smoke (like a smoke stake).

I dont really lose much power but it is a bit embarassing. My mechanic is good but has no clue what it could be.

Any ideas on what to check or what the problem may be ?
