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.

Well, the Nismo intakes are 2.75" ID, I somehow doubt that those or the TB's are an actual restrictor, but I suppose it's possible...
The "cut" so to speak, is between 6200 and 6400 RPM. This corresponds with the point at which the MAF flow #'s clip. Basically it hits like 266 G/Sec and stops. (I think it's 266, it's been too long since I looked at it, I need to start logging that stat now I guess)
Problem is, I don't know how that reading possibly affects anything when the MAF Volts continue to climb/index on the table.
I may need to send some data to a pro tuner and see what they think might be happening... if the lump at the end there extended from 6100RPM and then rolled off closer to redline, I think we would see much more impressive top end numbers. It seems aborted, the way it is right now.
