Message: [QUOTE="The Butcher, post: 1211590, member: 17789"] I'm jealous. I'm getting about 12.5MPG per the lie-o-meter (mixed freeway and stop and go surface street traffic), which I would guess equals 13-13.5MPG since I'm running 38's. At 30 MPH my speedo is dead on, but I think at 65-70 I'm off by 5-7%. Mind you, this is with deletes and Innovative Extreme Street tune. Maybe it's my 4.30 gears that are making me get worse mileage than you, but man does this truck scoot. I put the Superchips on first before I deleted. Ran it for a couple thousand miles. I actually was VERY impressed with their DPF on performance like Ipkyss said. Tow tune was pretty marginal, but their performance tune makes a very noticeable difference, and the truck is still just as quiet as stock. The thin would fly, but you wouldn't have any engine noise augmenting the experience. It was actually kind of fun because of how stealthy it was. Their shifting sucks though if you choose the straight stock file. Ipkyss mentioned you can turn of torque management and that would help their slow/de-fueled shifts. My mileage went up at first on their tune, but after a couple of tanks the regens started increasing and it killed the gains I had made. In fact, I think it got worse mileage because of the increased regens. [/QUOTE]
