Great post 4x4.
I have basically the same mods as you, except B&B headers & exhaust vs. Milltek. I can't imagine that there would be much change due to that.
I am one of the fence sitters. Let me ask about the torque. I think the softest spot in the rev band is under 4k rpms, and the
plenum seems to really address that issue.
Do you notice a much improved accelleration through this band, or is more of a "I think there is a difference"?
Also, I still think
RSS needs to resolve the hose issue. It is unacceptable that you had to modify your install to that extent IMO.
Take care, and enjoy your mod!
