I was wondering if you guys could give me some feedback on the setup I'd like! All your advice- even against these mods- is much appreciated, I admire many of your setups and trust your expertise.
I'll start with what I have:
A Stillen true dual exhaust, a Stillen ram air intake, a Nismo flywheel, a grounding kit I made, and a catch-can I made
A neat article on them
This is what I want:
I finally have made enough to get a plenum spacer and tune the car. I know I want the Motordyne 5/16"
Unfortunately, I'm still confused after all of my research on the best way to tackle the ECU. Are my modifications far enough outside those 'pre-mapped' parameters piggybacks use to guarantee effectiveness? (I have no intention of going FI.)

If you guys could tell me the best way to optimize my Z I could sleep at night hahaha
Thanks again,
Matt
