Need Advice on Carparts

[NecioVato]

Hey everyone,

So I currently have a 2017 Nismo 6MT and have most of the power mods other than going FI (intakes, HFCs and CBE). I did get my tune from Jotech which is local to me several years ago.

Currently bought the following and haven't installed just yet - Fortune Auto 500s with swift springs, TE37s and the SPL parts to keep it all in alignment (FUCA, rear toe arms, rear camber links and the lockout bolts). I am currently trying to figure out what is next and thought I would ask for advice.

I have thought about the following:
1. Coolerworx short shifter - I have read the reviews and seen the YT vids about it as well - seems like a great mod but I daily my Z and wondering - is this the best route for the next mod or go with something more OEM+ like the Z1 shortshifter?

2. Lately my Z has been feeling slow (butt dyno-wise) and wondering if maybe having it reflashed and going with ECUTEK vs the UpRev that I have would be a good idea - was thinking of going with Seb and doing a remote tune bc again - it just feels slow for whatever reason - no codes are being thrown etc.

3. Start saving to go FI - this one while I feel like it would be fun to be supercharged - overall I feel like all the hidden costs and reducing reliablity is probably not the wisest decision - I have about 82k on the odo and I'm not the most mechanically inclined type of guy - I have friends who help me out a lot to be honest.

4. Maybe focus on some other mods that I have on my list - morimoto lights, oil cooler (based out of TX although never really had too much of an issue to be honest), and if I was to eventually go FI....would make sense.

5. OTHER - maybe I am missing something obvious and would love to get some input from others on suggestions etc.

I know I should do 'whatever I want and not worry about what others think' but i just wonder what others might prioritize is all. Really leaning towards a short shifter and or looking to do a retune to see if its just me or maybe another tune would open things up a bit. Anyway - thought I would ask. Thanks in advance
