Results

A the rear wheel: 131.28 hp, 78.96 ft-lb

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.)

 

Is it a big change in the power when your riding now.

 

Yes , there is a noticeable difference at 5,000 rpm and above.

 

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!)

Thanks!
