MFM, because it averages the intersection of the 12 PALS subjects, will appear more smoothed than AFM. The range is likely to shrink.
Also, if you mean the range of your volume is wider than the range of either AFM or MFM, then that could mean some of the extrema in your volume are outside the cortical ribbon. But you say "original 2D map" -- not sure what you mean. Doesn't sound like a volume. Just know that on Metric settings, you can adjust the user min/max to whatever you want. That gap at zero is part of the palette you selected. There is a version of that palette without the gap. You can try other palettes, too -- see D/C: Metric Settings. I often set the scale min/max to be equivalent, based on my degrees of freedom, to p=.025/hem or p=.01. It's your call how to set the min/max.
