Looking at the 2 graphs layed over each other,
Yes, it's way richer which can be partly attributed to less manifold vacuum @ WOT,
The amount that's richer by if corrected would bring the power up to near where it was,
But without any other changes, it's unlikley to beat it.
Of note,
The charateristic of the power has changed. (Almost like the Vtec point has moved)
Though the original output is a little leaner than it needs to be through most of the graph,
That aside, it has the charaterisic of advanced cams & a long pipe style CAI,
The current output has the charateristic of retarded cams & short ram intake.
If there was no change to the intake system leading to the throttle,
You need to confirm the cam timing...
Ideally you should have the car tuned with both intakes & use the best.
