Tune on my 200,000mile c1500

Do you think 200,000 miles is to much to put a programmer on the truck? I'm worried about it causing problems it's been a one owner and always serviced regularly clean truck would never know it has 200,000

I have it on my todo list and my truck has 220k+ miles. What're you plans w/ the programmer?
