Let’s start by making pairs to see what we have

14 17 08 87 87 13 00 90 84 86 89 92 03

Interesting range. Look at where number positions should be, they all start with 8. We know that in Ascii, numbers range in the 50s, let’s use a ROT-3 on every digit

81 84 75 54 54 80 77 67 51 53 56 69 70

Convert decimal to Ascii
