Bogged down sound

What is your question?

My TB makes a bogging down sound when I accelerate from complete stops. It goes away at about 20-30 mph, and it seems like its using more fuel. Some ppl say this could be the Transfer Case going out. Any suggestions? No the Service Engine Light has never came on, but my ABS light is on because I'm having problems with my front hub assembly.

First, try using a can of Seafoam in the tank to clean out the fuel system. If this doesn't work, try changing the fuel filter, next step would be to have the catalytic converter checked, still nothing? Have the fuel injectors checked, and if that doesn't work...take it to Porsche for a diagnostic.
