This calculator is telling me that intake close occurs at 37 degrees ABDC @ .050" That is my calculation as well. That is equivalent to 64 degrees ABDC @ .006". COMP CAMS states 81 degrees at ABDC @ .006" on the card.
This calculator is also telling me that COMP is incorrect.
What numbers did you plug in? Can you screen shot?
Whatever you did got what COMP was getting.
