GTi6s do have a knock sensor so theoretically they'll run a bit more timing as long ad the conditions are ok... But in our climate, you're very unlikely to notice any difference IMHO, vpower won't help the engine really, you've got to consider they're designed to run on 90-93ron in countries with bad fuel supplies... There's an option in the ecu to run the ignition timing retarded for places you can only get 85ron... So putting in 97 isn't going to make any more power...
There's no difference in joules/mol from vpower to normal fuel... Infact vpower diesel has less joules/mol than regular, only advantage is the cetane number so technically it'll burn faster and produce more work done...
If mapped on vpower and the timing bumped so you might see the gains of the increased octane number, but on a standard OEM car, you just won't notice it... I've tried both on my GTi6 and cannot discern a difference... A cold night makes 50x more difference...
