So after reading this post today, I was curious about the supposed temp issue so I decided to go out and test it myself on a hot day (was 90 degrees here in the shade). So I went out and beat on my car for a couple hours. It was a mixture of stop and go traffic with multiple red line runs mixed in from lights. I even cruised around in 4th at about 60 mph for a while. Beat on the car some more....couple more red line runs followed by traffic...and I could not get the temp to rise above ~250 degrees (give or take 5 degrees - could have reached 260) no matter how hard I tried. Limp mode was NOT happening.
So what this means to me, is there is no way in hell I will ever have the car go into limp mode unless I absolutely HAMMER (borderline destructive) on the car on a very very hot day. If tracking the car means I have to beat on the car more than I did today, I will never see the track. Moral of the story, IF you like to drive extremely hard on the street, you probably wont be hitting limp mode any time soon.
This post has the feel of "this car will go into limp mode unless you drive it like a grandma"...which couldn't be farther from the truth. The car performs as it should under street conditions in my opinion.
Anyways, just my two cents, take it for what its worth.
Edit: It could also be that my "driving hard" is not nearly as hard as someone elses hard
...but i doubt it.
