Correct me if I'm wrong, but both GM and Ford "MAF" systems still run 
a MAP sensor to deal with situations that the MAF can't handle 
(transients, I presume).

MAF sensors can handle all the transients you can throw at them 
provided they're set up properly, ie, they're sampled correctly and 
you have some form of manifold filling compensation.  I suspect that 
the additional MAP sensor is for added functionality, perhaps EGR 
control or maybe something else.
