The engine has a slight lag in power changes due to the free turbine design.
With regards to performance, there are several different dash number PT-6's out there. I've flown -20 (500HP), -21 (550HP), -60A (1050HP), -67B's (1200HP). The lower dash numbers tend to temp out a lot quicker, especially in the summer.
Good engine, easy to run, damned near bullet-proof.
http://en.wikipedia.org/wiki/Pratt_&_Whitney_Canada_PT6 has a lot of good info.
