Any idea what could be causing turbo surge on stock RB25DET turbo?

Lol Ricky I dont mind at all, if Stav doesnt mind his thread being filled with techno babble :)

The mapping is a curious one but makes sense when you think about it :) Good luck.

 

Great! i would be very interested on just what happens during stall/surge on a centrifugal type compressor, IE if any damage or detrimental effects occur, ever since fitting my single i have had quite marked stall/surge on closing the throttle, have had the same effect on two or three different turbo cars.

and have always thought nothing of it, and that it was stall and did no real harm, so getting to the bottom of just whats going on would be good:)

 

Stav, glad you have a possible solution, will wait to hear if it gets sorted via mapping, or you find a leak.
