If you look at the cam specs in the appendix, you will also see that there are two different SC cam profiles that correspond with the two different timing settings you are seeing. I would think that the correct timing will depend on which SC profile you have. I know we always read about using the SC cam in our turbos, but no one ever really specifies which SC profile.

I had my 930 cams reground by DRC, and he sent me the timing is 1.4-1.7, which tells me these are the later SC profile.
