The modification indices are based on the score test. The model
Chi-Square test is a likelihood ratio test (LRT). Only when the sample
size becomes very large, they will converge to the same value. In
particular in small samples, they may diverge.
Modification indices only give you roughly some information about the
impact of relaxing a single parameter (one at a time).
