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.
Received info that the Altezza track car will be running at the open track day in Speang last Sunday...so sms some of the guys and down we went to the track to watch the maiden run of the awesome Altezza track...
