370Z Nismo undeteced upgrades

[StuNismo]

Hello PH's,

I have recently purchased a Nissan 370Z Nismo, 2016 as a weekend driver. It's a wonderful and great car to drive. The only downside is It’s a pain in the arse to keep clean bloody hate British weather. Anyway less about that, the real reason I’m drafting this post is that I want a little bit more mid range torque from my 370Z. One of my sticking points with the upgrade is that I need the upgrade to go unnoticed via the main dealer diagnostics.
As you can imagine I have spoken to a couple of friends and they have said to purchase a tuning box. But one of my close friends said I could install an induction kit or performance exhaust which should give anything from 10+bhp, He then stated that I would have to remove the induction kit if any warranty work was carried out on the car. The only issue my friend mentioned is that Nissan may use a system which can detect you have installed an induction kit and or new exhaust (This could be due to Nissan GT-R’s and etc…. there diagnostics systems may be more advanced than other manufacturers).

So my question is, is there any undetected upgrades I can apply to my Nissan 370Z Nismo, 2016???

Many Thanks
Stuart.

Maybe ask Nissan if they can help with official parts, but otherwise no. Any modifications would rightly invalidate the warranty on any part it affects.

This is what I was thinking. 🤔 many thanks Mike
