Reading the Dyna manual is where he probably got the gear change every 10 mph. If memeory serves me right thats where my 96", 6 speed is supposed to be changed (per the manual), but after some ride time one figures out where the sweet spot is in the RPM range.

Pinging when you roll hard on the throttle is called a spark knock and it's because you're running too lean. With a power commander and modified exhaust/air intake, go get a good dyno tune and you'll stop pinging... You can add all the oil additives you want or run at whatever rpm you want, but that won't fix your problem.

How do you know that? Did you hear it?
If he is no longer having the issue with simply changing when he shifts, it is not truly pinging. Pinging is a function of high compression and low octane gas causing inefficient combustion, more than shift points.

Ok... what if you get it professionally tuned by Star Racing (after having it tuned no so professionally by the Harley Dealership) and when the RPM's are low and you crank it, it pings a little until the RPMs build, or you down shift and it goes away? Do you think it is still a simple dyno tune issue? What if you never have a ping problem if you keep the rpms up?
