I've hit 50k miles on my 2018 with one glow plug replacement and the EGR cooler recall done. My truck has had the GDE tune since 15k and runs smoothly. Any 18 owners here experiencing issues?
just hit 50K as well, only issues are basically false alarms with the odd sensor that resolves on its own without incident. no other issues. Just completed the safety recall VB1 though I had no coolant issues, then installed a Banks Derringer & K&N filter very happy with the results. So far, best tuck I've owned.
