I do have calterm but I’ve never even opened it on my computer so , I’ll plug into it when I get home today and check it out, try to get you some more info

It does not matter what the part#'s say ... the 12-point nut is the fuel efficient, lighter turbine, fuel efficient version of the turbo and is not made for heavy-haul applications. The 6-point nut on the cold side is the thicker, titanium turbine version of the turbo made for heavy-haul.
