Your old question will go with my old answer.
Look at the sticky (top of page) in the tuning section.
Get a tuneecu cable and DIY.
Look at Dikmans tune list for the Triumph tunes.
Consider pulling the cat, load AK's or my tune.
You don't mention is the Arrow can, street or race. Does make a difference.
Air box mod's also in the sticky, also look at hole in clean side of air box. (since your there)
