They call it Rocket for a reason....it's pretty potent the way it's delivered from the factory. But what the factory chose tuning wise would certainly have to be something that is good for most buyers. Everyone will ultimately want to change SOMETHING, for all bikers do, I am pretty sure. But you can have an idea, but if it's not a specific result that you can name it's hard to map out a plan. And when you have nailed it down to specifics, you then tally up what's needed to make it happen....and it'd probably be more than one task or one new part. For in fact to get what Triumph has given us, they've had to select parts that work together to give us that. If we want different we are going to have probably to get some different parts that will work for what we want. The only thing I can see happening with all stock kit, is to derestrict the secondaries if you have a restricted tune. I don't think the Roadster does, but the Touring does, and that's what shapes it torque curve, albeit at the cost of some horsepower at the top. We can derestrict and get Roadster like performance, but we might loose just a bit of the lazy cruising that makes a touring bike possible. Or you could improve the factory exhaust with something a bit freer flowing, AND give a better tune to match, but not necessarily a Roadster tune, and you might just have a bike with nice touring manners, that will still gather up it's skirts and go when you twist the wick all the way back. Alas, the secondary throttle plates could be removed altogether, you add pod filters to each throttle body, and put a fancy exhaust on, then you will surely need a proper map, and probably there is already one that someone has made for such a set up. But that's a lot preparation, and modification. And it sounds like you would like not to go with heavy mods. So I think you already have a good tune for what you got. Though there may be a couple tunes you could try that moves your torque curve around and could possibly find another 10 or so horses. So long as you make a backup of your stock tune there's no reason not to try what's out there. Just be sure to choose a tune that matches your equipment. You can really make an engine go badly rich or way too lean if your tune is wild and you don't have the pipes and intake to match.
