Default Magnum 52 RFS tach reading

Magnum 52 rfs APC 12x6: 8900 to 9200 running slightly rich. Engine is somewhat new, about 1/2 to 3/4 tank run through at 1/2 to 3/4 throttle. (Installed on Global Blue Max). Idle is okay at 2900 to 3000 but will fall off under 2900. Do I need more break in and is the power in line with other Magnums

10,500 on 12x6 MA (nylon)
10,500 on 11x8 MA (nylon)

This is a 1999 production model with the longer, thinner muffler., shaped like the OS52 muffler. The factory switched to a shorter, fatter muffler about 2 years ago or so, which hurt performance, but was quieter. They have since re-launched a longer thinner one that is quieter and but also has the higher performance as well.
