Just on what you said in your first post, I would agree with everyone else, however, there are a few things to consider.
What is the ambient temp of the trip going to be like or what is it like usually for this time of year(or when your doing the trip)?
And at what speed do you normally travel on this trip?
The main concern for those two questions are EOT and ECT(typically two things that most people don't get gauges for(or some type)). I have run ~90mph in 60-70 degree weather for about 30 miles and my egts ran 800 and something and my tranny temp was 180(after rebuild), but my ECT was creaping on 218 and my EOT was about 227.
Depending on how fast you run, how hot your tune is, and how hot the ambient temp is will help to determine if a hot tune is as really safe as people on here seem to think it is. On the face yes, it could very well be safe to run either tune(I'm not saying it isn't), but there are other factors that affect how safe a tune is on travels that must people tend not to gauge.
