  We involve the galactic halo observational data to test the weak field
General Relativity involving the cosmological constant. Using the data for 15
hydrogen (Hi) VLA super spirals and the Tully-Fisher relation we obtain
constraints for each galaxy. The results are consistent with previous results
for spiral galaxies, as well as with the scaling relations for the halos, thus
confirming the efficiency of the use of dark halo data and Tully-Fisher
relation, including the baryonic Tully{Fisher index (BTFR), for testing
modified gravity models.
