I would rather use the MS by itself then piggyback an EIC. Until we know exactly what the stock PCM does in every situation, we will have a situation where the left hand doesn't know what the right hand is doing, and the right hand doesn't know that the left hand even exists. I am sure that the EIC works, and works well in most, if not all, situations. I would just like to use a 1:1 regulator with a sane fuel pressure. Lying to the stock PCM doesn't seem optimal, either. It's just my quirky opinion, though.
