  We study the conjectured duality between the $\mathcal{N}=6$ Vasiliev higher
spin theory on $AdS_4$ and 3d $\mathcal{N}=6$ superconformal Chern-Simons
matter theory known as the ABJ theory. We discuss how the parameters in the ABJ
theory should be related to the bulk coupling constant in the Vasiliev theory.
For this purpose, we compute two-point function of stress tensor in the ABJ
theory by using supersymmmetry localization. Our result justifies the proposal
by arXiv:1504.00365 and determine the unknown coefficient in the previous work.
