Does anyone know if you can revert the AWD transfer case back to Porsche specs? I read somewhere that the touareg and the cayenne have the same 4wd system but the vw and Audi have software on them to run at a 50/50 split. I'd like a way to go to 70/30 like the Porsche has. The transfecase is set mechanically to be 70/30 split but somehow the computer forces a 50/50 split. The reason I would like to do this is because I drive a rear wheel drive car in the summer (Porsche 951) and I am used to the rear coming out and not pushing like the touareg does in the snow. A bit of a tail out condition is controllable but i hate understeer. Thank you for any help.
