Default Can hydraulic lifters cause inadequate full power?

What would that tell me, aside from that it makes more power when you reduce the detonation
margin and violate the TC for the engine? I run autofuel often, so advancing the timing isn't a safe
(or legal) option. It should be able to make the power at book timing.
