There are plenty of good tuners who don't use TuneECU or Tuneboy to dyno tune. If you can find a tuner who who uses TuneECU or Tuneboy (which costs just to use it), you could do that. You need to open the secondaries anyway with one of those programs. If you can find a good tuner who uses Power Commander only, do that. You can get good results either way.

There is a list posted with the Tune ECU site.
