Two very good tunes of one Ferrari. Tune 1 is just that wee bit looser (a bit more Ferrari like). Tune 2 is a bit more solid...very easy to get round a track without the car trying to kill you:). Very close in lap times ...I was 1 second quicker with tune 2 around Silverstone but somehow I still prefer tune 1. It's just got a better feel for me....I just need to practice more with it:)
