Worth verifying with your scan center, but I believe your timing should be "alt+z2" for even number of slices. Depending on which scanner, which software version, and which sequence of course. The incorrect timing information on slice time correction could play decent havoc on your analyses. Particularly with such a large TR window.

Also, as Bob mentioned a censor threshold of 3.0 is massive, and doesn't correspond to 3mm/3degrees of movement, we do the calculations on euclidean distances, hence the recommendation of 0.2 or so. That would at least put it in the range of other software packages like CONN for censoring motion out. You may also want a -regress_censor_outliers 0.1.

Change those two things and re-run and get back to me!
