That is a good combo but I'm afraid you should be making more.
Looking at the graph you seem to need more tuning.
Did you have any knock retard?
That combo should be good for 430/400 numbers, over 420 for sure.
Cats anf FIPK are not robing you so much, those are good cats

Tuner spent a lot of time getting it where it's at. He's a perfectionist and has lots of experience. Don't know what to say.

I'm interested in the comment on the FIPK. I'm under the impression the K&N FIPK is a good intake. Provides power gains as opposed to "robbing"?
And as stated, the cats are full flow through the center. No restrictions.

I use it and I can vouch for it. works best with Ultra-Z hood or similar front ram air.
