So I came across this today when I went to go purchase my oil from Amsoil. I’ve always purchased a wix filter from them, which was a 57060. GM has put out a service bulletin stating what some other members in this thread already know, that the required bypass setting for the LT1 is 22psi. I don’t think Wix’s new filter is available yet, but there is some more information about this on the corvette forums.
