Yeah, I fill up 75L tank and it chews through pretty qucikly... but you dont buy a gtr for fuel economy! Driving around city giving it hits here and there it manages around 300km a tank, highway driving bout 350 - 400km.

Oh, and in this heat, my car refuses to drive without octane boost, so youve got 75 litres of Optimax/Ultimate/Synergy8000 and $15 - $20 per bottle of Nulon Octane Booster which will do one tank.

And I'd reccomend against using normal PULP, as my car and a few other GTR's around the area, if the temperature is over 25-30 degrees, even on just Optimax and Ultimate they will detonate and misfire and splutter down the road.

My 70L tank gets me on average a little over 500km. I usually use BP Ultimate, but failing that I'll only use Synergy8000; I'm not touching that OptiMax crap. I'm only running a little over 210kW though.

Amaru: if your mates and your car are pinging then I suggest you get a good tune... I don't need to worry about it and I've driven in 30+C conditions.

I think it really depends on how heavy your right foot is. My fuel economy is based on may daily driving habits - it's a 55km journey to work with a mix or peak hour and freeway driving. I don't spend a lot of my time boosting (but I do give it a squirt once or twice in that trip).

My car is boosted - it's running approx 14psi.

    • Resizing injectors in Nistune can be done a couple of ways, and there are a couple of ways that you can make a mess of it. The tuner needs to be really aware of the effects of whichever approach he uses (either K, or TIM). They are both easy enough to "get the injector size right" to run the engine. But little details like old start enrichment and hot start are affected differently, depending on which boxes you check.
    • Pretty safe to say almost everyone that has tuned their own car has experienced this issue. The difference being that we have our laptop in the car and when it happens, it's literally 10 seconds of tuning to sort it.  Would you be happy to plug in your laptop and sort this yourself? It is a very simple process and there is no risk of harming your engine (if you are worried about that). 
    • Yeah thats the next step now, either they wil or i will take out for a drive to work and go straight their after work and see is we get the same issues 🤞  thought i try my luck here too, never know someone else might have had the same issue but thanks for the reply 
    • Basically your tuner needs to drive it for the 30 min (or whatever) to create the same conditions then check the ECU settings and sensors at that time. They may not be excited to because that takes them 30 min rather than just opening the bonnet and seeing the problem straight away.... Hot start is generally not as tricky as cold start, but there would be a table for fuel enrichment vs coolant temp as a starting point
    • Yeah, they all cant say anything for sure as everything is working fine . Said unable to find an issue untill it stops again. Could mist likely be CAS wiring or IAS valve issue but again not 100%
