I was told that the v4 will communicate and work properly with my 2005 gto ls2? It has an OBDII port but from what i can tell this is not the case, figure this is the best place to find this out for sure. Also if it can be used how come under select vehicle there is no option for the GTO or any other ls2 for that matter, do i have to update download more "select vehicle" list or what, thank you for the help. PS I have the full pro version license
