Greetings from Idaho.
Question about DEF usage. I installed the GDE tune when my truck was new and had just 350 miles on it. Now at over 60K miles I am adding 2.5gal of DEF while pulling our travel trailer ever 2k - 3k miles driven. Is that normal? Still getting mid 20s when not pulling the TT and mid teens when I am.
Thanks, Craig
