Feedback on my impending mods

KingJoseph

I posted a similar thread on the Northwest forum, but preceded it with a question regarding where to get a tune in the Seattle area.

However, I figure my Nismo brothers may be able to more effectively answer the latter part of my question:

My FI CF exhaust should be on the way within the week, I already have Berk HFCs installed, and I'm on the verge of pulling the trigger on the Z1 post-MAF tubes + K&N drop-ins and Motordyne M370 intake manifold. Does this setup collectively warrant a tune? Does anybody have close to this exact setup on their Nismo? I'm curious about subjective and objective results... or if anybody thinks I'm making a mistake with any of these mods. This probably all I will do to the vehicle performance-wise.
