Its very odd for a car to be datalogged and left on F5 unless you need such a rich mixture. Without an uprated HPFP then F9 is far more likely to be correct.
Did they give you any copies of the datalogs?
no did not give me any copies. i queried about putting it on 9 and they said that was for race octane fuel?
PDT - what will be the problems of running it at 5 - simply dont need that much fuel on a stg1?
cheers
