Ya, I don't think that is really an option. I live a few miles from them and while they are a top notch Harley distributor with huge inventory, there isn't anything there that isn't Harley. Nice folks and good reputation for the Harley crowd but they aren't going to let you go back in the shop bays and work with one of their tech guys.
If I'm going to pay hundreds of dollars for a dyno tune, I'd like the assurance that they are familiar with tuning Triumph Rockets.
