This is what I kinda expect as well.
I've never tuned a car, just installed parts, but just being on Honda forums for 15+ years you can assume that you're not getting 25hp with just an intake on engines like these.
The good thing with I/H/E is that those *can* be compatible with S/C setups so its not a total waste, if from that point you want to go all NA, or S/C.
Plus in addition to the curve, a lot of NA boxer engines have that very pronounced dip there, even in Porsches, even my Civic SI '02 has it (albeit a smaller one) and I'm guessing things like VTEC were made to remove that dip, or put it higher in the rev range.
I'll probably should ask questions like this in the engine thread.
Anyway, I don't want an overly loud car, so at most I'd do I/H + Tune and maybe a midpipe (or conservative exhaust, like the TRD), if just for the weight loss.
