Here's what I would do.
First choice really depends of whether or not your dyno guy is familiar with Tuneboy or if he will charge you extra to learn. If he is hesitant to learn or the cost to do so is over $500 (keep in mind with the Tuneboy he will probably have to make 10 or 12 runs and shut the bike down between runs and make changes to fueling maps then reload the map into the bike, with the PCIII fueling changes are made by the computer on the fly).
If he is not willing to go the Tuneboy route and odds are if he is not familiar he probably is a dynojet user.... I would get the Tuneboy and PCIII. Have him dyno tune your bike with the PCIII. Load in the tune I made in the trading tunes forum for use with the PCIII and Tuneboy combination. That way you get the ignition remapping, secondaries opened and speedo correction. Plus you have all of the other goodies such as diagnostics that comes with Tuneboy.
You may actually save some money going the PCIII and TB route if the Tuneboy only dyno costs more than the PCIII with dyno tune. Tom has the PCIII and Tuneboy combo. If I can't get someone in my area to dyno tune the Tuneboy I might go the same route. Tom's bike runs really good and pulls strong.
