Maybe others have had better luck then I did with this setup.

Did you remove the negative battery terminal and reset the ECU? Or get a tune afterwards?

The ECU bases WOT response on closed loop look-up tables + MAF input in every other car I have owned. This wouldn't effect that.

Even if it did, after a certain number of key on/off engine on/off cycles, it should adapt, no?

I gave up on making mine fit also. Plus on my Nismo the breather tube on the driver side is different than the passenger side but on the tubes they are set up the passenger side way, if that makes sense. Just stuck my K&N drop-ins, in and called it good. I Get my Fast Intentions exhaust tomorrow tho

I get my FI exhaust tomorrow, too!
I did finally get the tubes to fit - had to trim about an 1/8th of an inch off the passenger side. There is a noticeable difference in throttle response. A lot more than I would have ever though possible just going from the corrugated tubes to smooth tubes.
