I had a predator tune in my 2008 hemi and removed the top speed limiter. My wife was in premature labor in a hospital 97 miles away. I called my boss as I was leaving town and he called me back as I was pulling into where my wife was--time stamps on the phone were 56 minutes apart. My calculations figure that at averaging 104 mph.

No not a great idea especially not having speed rated tires on at the time but the vehicles can definitely do it. Whether they should or not...
