I've found the following websites to be very useful for playing "What If?" with propellor pitch.

Density Altitude and Percent HP Available

English Units
http://wahiduddin.net/calc/calc_hp_dp.htm

Metric Units
http://wahiduddin.net/calc/calc_hp_dp_metric.htm

Also, the following propellor efficiency calculator is quite useful if you have some actual performance numbers (TAS at RPM at DA)
http://www.gylesaero.com/freeware/propcalc.shtml

If anyone has questions about these, let me know and I'll try to walk you through how I've used them.
