15 Limited Knocking
15 Limited. Stage 1, had tuned at the dealer when new with the HD SE Race Tuner. It always has sounded like marbles knocking around in the engine under heavy acceleration, full throttle above 4000 rpm. Other than that annoying marble sound it runs great. I also noticed it does it more when its hot out. Is it too lean? Normal?

Then I'd suggest you are, in fact, running too lean still.
I had a dealer tune done. The first time, it pinged (pre-detonation). I checked the AF ratio with my power vision - they'd set it to 14.4 - I went back and had them reset the default to 14.0 and the pinging disappeared.
