Does anyone know what tune is used for the Red sport and what the HP increase is.

You can use JB4 or a real tune from ECUTEK.

really tune with bolt ons, you can easily achieve 550 plus WHP some get 600

This Z is putting out B58 numbers:

"We've been trying to grab a Z for BMS development but so far have not had much luck, but fortunately a local customer dropped his car off for a couple days so we could do a little JB4 dyno testing with it.

The Z is 100% factory, auto, with a couple hundred miles on the clock. Fuel for baseline and JB4 quick install runs was ~93 octane (91 + 2 gallons E85), later we added another 2 gallons E85 to get up to around E30. We do have a couple 91 octane runs we can share later but with the car being so new didn't want to push the tuning on 91.

Baseline ~93 oct average run was 364whp/352wtq. (Factory power on straight 91 was around 345whp.)

Using JB4 map2 in a "quick install" format (no fuel wires, no EWG connectors) we dialed power up to 401whp/459wtq. Pretty solid gains for a 30 second install without having to reflash or touch the ECU.

To take things a little further we attached the optional JB4 EWG and fuel control wires (adds around 30 min to the install), added a bit more E85, and got power up to 426whp/487wtq. At the higher boost levels we found we were fighting fuel pressure and possibly the turbo turbine sensor mapping, so decided to call it a day until the car has more miles on it so we can further evaluate. Overall though, awesome platform! For those who don't want to flash tune the JB4 is going to be an excellent tuning tool for it."

I heard the JB4 quick setup is an undetectable plug and play solution. Is this true? Asking for a friend.

JB4 are plug and play and don't rewrite the ECU so if it's removed it can't be detected.
You have to be cautious using JB4 and make sure that you are running proper fuel.
With the Z already being at 400hp, the JB4 won't make a huge difference.

The graph above seems pretty impressive to me for this type of solution, or is it not a substantial enough gain to notice? Would 93 octane be fine? Pretty easy to get in my friend's area.

I imagine it would cost the same as the Infiniti platform so $678.
There will be a noticeable difference.
93 octane would be the best to run with it.
Personally the cost for the gain isn't big to me, but that's because I would rather just do an ECUTEK tune, but that isn't what your plans are likely, since that would actually flash the ECU.

If you want to keep everything under warranty, the JB4 is a decent option, but I would suggest refraining from buying it until you actually drive the Z, because the base power will be good as it is.
The JB4 basically tells the system to push a bit more boost.
If I went back in time I probably wouldn't have bought mine, again though the reasoning for me, is I would've been satisfied with the base power of the Q, and later would've gone with a full real tune.

That’s the plan as well. I’d rather just do some other things for a few years. Then close to end of warranty I’d just tune it with ECUTEK.

while waiting, do bolt ons,suspension and body work.
