I'm just taking a guess here, but supposedly some '93's came with the later style transmission(4L60E rather than the 4L60) in which case you would have the silver PCM rather than the black ECM, nobody has any concrete evidence that this is true, my guess is also it would have the MAF as well since that came in '94.
Also teh intake manifold would have a crossover tube.
But like I said, it's only a guess and probably wrong.

More than likely you have confused the existance of some 93 mule cars for cars produced and sold in 93.

In both strategies the o2 sensors gives the PCM information so that it can predict fueling requirements, in both immediate (short term) and for future (long term) fueling needs. In this sense if the sensor sees that that its a bit rich the PCM will trim the fuel back or add if it goes the other way. In both the early and later MAF cars this same logic exists. While one maybe a little more accurate in its coarse adjustment than the earlier SD logic. The final control is nearly the same in both. I have seen SD cars get upwards of 30 MPG in stock unmodified cars. And I have seen MAF strategy engines do a bit better than 30. The main reason GM reverted back to using the MAF systems was strictly for emissions requirements.
