New Engine Running Hot

I put a new 103 in my 2010 limited under the long block program. I had over 123,000 on my last engine. The problem I'm having is that it is running so hot, that it has burned my blue jeans (3 pair) and melted a hole in my Harley Davidson rain pants (through the protective shield). Took it back to my dealer and was told nothing is wrong with it but I should put a tuner on it! This is a new motor so i dont think I should have to do anything to it. Everything is still stuck and I had no problems with my other motor running hot. I now have 7200 miles on this I just worried that running this hat that many miles will probably ruin my motor. Any suggestions?

Was your old motor a 96? If so, your running lean with the 103.

Put an AFR on it so YOU can see WTH is goi g on.
Up to that point, you are just guessing and getting led around by other peoples information.
