Power chart for an Extreem IO-360 or Superior IO-360?

[ao.frog]

Hi.

I'm just starting the breakin now, and the Eagle Engines manual says to start leaning to approx 75 ROP after the first two hours of flight and to fly at 65-75% power until breakin has occured.

Does anyone have a powerchart for this engine?
(IO-360-B1AD2 w/ dual P-MAGS & Roller Lifters, 180 HP, 8,5 compression)

It's based on a Superior IO-360, so I guess I can use a chart for that one as well?

I'm aware of the "48 rule", but after searching this forum, it's seems to me that a chart would be more accurate than the 48-rule.

Thanks.
