Us and euro gtr can run ron 95 but factory mapswill cut output, with cobb ap you are able tune the engine to run 95. I've got mine tuned at 1 bar stock everything 480whp and 1.2 bar 500whp however advisable to go 97 with that map.
Need some advice and view with regards to the problem i'm facing with my fuel pump.
When the fuel tank is full as indicated by the fuel indicator, car no problem. Run smoothly.
But when the fuel indicator drop to the remaining 3 bar (full 8bar), it started to choke and even when you press accelerator, i just won't go. Can't even rev. And died off. Try to restart, it won't start.
After that happen, once pump petrol to fill it up to full, no problem. What may cause such occurence...
