I'm pretty sure that Triumph installed multi-point injection (6 injectors)
onto their PI units. With a carb conversion you are going with throttle
body injection (1 injector in each "carb"). They are similar yet
different. I'm expecting that they'll also be electronic, not mechanical,
control.

I'd bet with the new injection you can boost HP by about 30 or so. You
can use a hotter cam with little ill effects because of the fidelity of
the injectors. That's just a guess tho, I'm not an expert.
