I'm never happy with the way they come, either. I put over $5000.00 in my 09 Bonnie to get 82.5 RWHP out of a 904 BBK, head work, cams, bored out the TB''s to 38.6CM, 813 cams, ABRK, AI removed, and on and on. I got the Roadster and have started on it. What a blast of raw power and torque.
It really gets expensive building them up. I don't know what they have out for the Tbirds yet, but I would go with the 1700 and enjoy it the way it is. (if I could).
But, if it is like the bonnie, get rid of the airbox and let it breath. I haven't even looked at the setup, but if it is running an airbox for filtration, can you get around it and run filters(pods on the throttle bodies). Big improvement on my bonnie along with free flowing pipes. After that, it starts to get expensive. All triumph tunes are so generic and lean for emission reasons. You can pick up alot with a tuneboy set up and using tuneeddit, you can get on a dyno and tweak it to run its max with a perfect A/F ratio and you can adjust your timing a tad to see if that gives you more power.
This is getting to long. Good luck with your bike and let us know what you do to it.
