Anybody who hates cats and likes Stingers meets my friend prerequisites...
I ran a full day in race mode this week. I'm in Texas and it was 98 degrees, but it was perfect all day. I never would have dared run race mode in those conditions all day without the regap.
Most of the time I keep the RaceChip in sport and the car in comfort.. unless I see a potential challenge pulling up ; )
Time will tell how well this works overall, but so far I'm more than happy.
