I had a question, as I can't find much on it. I have a 2011 6.7L with Spartan tune, (running 120hp DPF off) and occasionally run the war hammer. I usually drive it easy, but had a buddy want to see what she'd do the other day, and so I did.
The truck was dead stop, traction control off, and I eased it up, then WOT, the truck accelerated like crazy, with tire spin, and then it felt like it lost the power. Is this normal, or is there something I don't know about? The first 5 seconds were intense, then it just seemed like it lost it's power. Anyone else experience this? BTW it was on 120hp when I did this.
