Dyno shows before and after tune. (The "before" is after aStage I (air cleaner, pipes and tune) plus the new parts: cams, throttle body and injectors.)

IMHO your air/fuel ratio is all over the place if you look at the hp dips and waves correlate to the A/F ratio. If your A/F was done better you would not see the dips in the hp above 5k RPM and would run smoother.
And as far as DESTROYER INJECTORS go - waste of $$ and increase in tuning difficulty - UNLESS YOU ARE Forced Induction or Bigger Displacement. Stock injectors at 136HP tune, were max'ing out at 68% duty cycle - making a larger capacity injector UNNECESSARY.
Keep a eye on your Throttle Shaft. 58mm throttlebody's with stage 2 cams tend to snap throttle shafts and would be ugly if you engine ingested one.

I have a new VRod and am contemplating an Akropovic titanium exhaust, 58mm throttle body, injectors, tuner, and maybe the stage 2 cams. But I don't really want to impact streetability, and I'm generally reading that the stage 2 cams produce more power/torque up high but there is some sacrifice at the low end.
So, what do your recommend? You seem pretty knowledgeable so I'd like to get your opinion (and background!)
