I don't know what that little dip was, I'm assuming operator error or glitch. I had a few pulls and this run was the only one that had it.
Don't put too much into the gains from the intake in addition to my mods. It's been proven that the first exhaust/intake mod gets around 12-15 whp and the rest, not so much.
So Intake first? Probably 13whp, sure. But after Che/hfc, probably no more tha 5-7, and that'll be at the top of the rpm range. I could be wrong, as I'm no expert. We'll see once I get my gen3's.
