Green line: civic si 07 I/H/E + reflash
Red line : My previous civic ep3 with K20A2 I/H/E + KPRO

What can cause the drop at 6500rpm?

A/F ratio

Compare them to the plots on the reflash page at http://www.hondata.com/reflash_06_civicsi.html

Well, it is slightly the same shape with less torque and hp. Mine as no more gains after 7600 rpm and yours after 7900. I have a short ram intake, dcrh and evo2 exhaust. Maybe calibration of the dyno has an impact on the results.

But I still dont understand why A-F ratio become very rich above 7500rpm. It certainly drop the powerband....

What do you think!

For the second time.... Can you explain the AFR after 7500rpm. Why does it come so rich??? :shock:

The 12:1 AFR isn't going to hurt anything, and if nothing else, it keeps the cylinder temps safe at high rpm.. If I had to guess, you're probably only giving up a few hp at that AFR..
