I just filled up my tank with 100 octane. $103 dollars later.
Anyways, first imperssion, the car feels SMOOTH at idle.
The first time I floored it I didnt notice much of a difference, I still had about 1 or 2 gallons of 91.
On the freeway the car got up to 150 QUICK! after about 20 miles or so I got off the freeway. The car feels noticably faster not crazy faster but a noticable amount. The sound is great though. WOT you can hear the turbo spooling.
Downside is I've driven about 40 miles and used almost a quarter of a tank.
