Well... I did recall & re-read that thread.

Reason for another post is: I intentionally retard my CAM after that post and what I'm seeing is NOT what its supposed to be.

The engine seems out of breath and my boost comes on waaaaayyyyy later. Hence want to re-ask the question.

I know each engine is different, but I think someone (DonE?) had tried different settings on same CAM - hoping to hear from someone.

Sandman, how did you know 1.65mm/1.7mm is optimal for your engine?
What does optimal mean in this case?

thanks.
