[QUOTE="maxxedout, post: 1402340, member: 15749"] Just wanted to give this a little update... I'm still having the issue, but I can't tell if it's more of a turbo/air management problem or a fueling issue. If I tip into it from a low speed roll, there's just a complete dead spot at 1,700 rpm. Maybe the truck is lugging a little bit? I'm not sure, but I wouldn't think it would be hard to keep a VGT spooled around 1,700 rpm. To answer your question, yes, the truck is pretty smokey down low. Honestly, I feel bad that it lets a pretty good puff out if I get on it to pass someone. I tried a tune with less low boost fueling, and the truck was an absolute dog under 2,000 rpm. This thing runs like a bat out of hell on the highway, but the dead spot down low is annoying in stop-and-go traffic. I'm really tempted to give S-partan a try. Everyone seems to like that Warhammer X QR tune on the 15-16 trucks, right? I would assume it would run the same on a 2012 with some 2015 parts. I'm not really thrilled about the idea of buying a new tuner, but I would love to have this truck running a little better. [/QUOTE]
