It's a given that there is friction generated by the cam chain rubbing
against the teeth of the cam chain sprockets and guides. The question
is how much and is there a significant difference between the tension
the OEM automatic cam chain tensioner puts on the chain versus a
properly configured manual cam chain tensioner. We're not talking
about a complicated part of the engine.

It's an interesting thought experiment, barring credible empirical
evidence. And, yes, I question the evidence seeing that the person who
is trying to sell you the part is making the HP claims w/o conclusive
proof. No offense intended toward all parties involved. I'm interested
in what's the truth, not what other people say.
