I wouldn't worry about the absolute numbers...
What's good is:
1) the HP # is about right for the mods, and
2) that's a nice, almost ruler-flat torque curve.
It would've been nice to get an RPM scale underneath, but they didn't because of the RPM problem in the first place.
It looks like the secondary fuel injector transition could be tuned a little better.
How high did you rev the engine till?
It looks like a little wiggle up there, but it could be that you're banging off the rev limiter?
This top end RPM power isn't that important, because you spend very little time revving the engine up there.
