This past saturday i finally updated the tunes on my 16’ 6.7. I had been running the tunes from fall of 16’ when the , ahem, weight loss program began on my truck.
Once i uploaded the 400 tune and took a drive i noticed that i felt a slight surging. While driving at a steady speed the boost will rise and fall about every 10 a 20 secconds. I was able to feel a bit of loading on the engine as well.
It was rainy and about 40 degrees out. The truck has never done this. I even stopped and restarted the truck a few times witout change.
I emailed Patr*** but have not heard from them yet.
I will put the old tune back on for now.
