Just got my tune and put it in then burned a bit through Cleveland (as much as a Cruze can burn). Worth every penny! 0-60 in low 8 seconds which puts me on par with my last car so I'm happy enough. Can totally feel the change in power. Also if you run in eco mode at 65, putting it into performance mode moves you up to 68.
I had the get stabilitrak message pop up when tuning but when I shut the car off and turned it back on it went away.
