My understanding is that Dynojet does not have a Power Commander available for this bike. The dealer told me that the stock ECM that came with the bike has 3 settings already programmed as follows:
1. stock pipe
2. Arrow dual slip-ons
3. Arrow full 3-into-1 system

OK. Let's keep this short:
1) Forget Powercommander, it is a poor solution for Triumphs. If you need custom tune you can purchase Tuneboy which enables your dyno shop to modify tune in your bike's ECU direct. No need for Powercommander piggyback ****. But in your case, you don't need either.
2) The ECU only has 1 tune in it. The dealer has a bunch of factory supplied tune files that he can upload to your bike for a fee in the ballpark of 20$.
3) Remove all restrictors from your can. If it is a lowmount, go to your dealer and ask to upload "Arrow tune". If it is a high mount dual can setup, ask to upload "TOR tune".
Job jobbed and no worry of running lean as the TOR and Arrow maps run a bit richer. TOR tune has more grunt down low and is a bit richer on fueling. Arrow map has more aggressive ignition timing, runs a bit weaker down low, but has more power up top. On some setups the Arrow map might result on pinging, if this happens just go back to dealer and revert to TOR tune.
