If I can figure out what is slowing the system down above 7k, I think I could get some pretty insane numbers.

Knowing you got the FI Exhaust and PPE header, your next step from what I have seen is the intake side.
I dont know what is the diameter of those Nismo Intake but you might want to look into a bigger TB and intake tubbing if they are too small.
If you remember, I mentionned all of this in my thread and at both occasion where I tested back to back , there was gain of 7-9whp with a bigger TB & CAI & Maf Tube.
