Just wanted to pass along the great experience I have had with this tune. I researched many places and this tune did things that most others don't. The truck has much more throttle response and low-end grunt. The truck feels much lighter and is much better in drivability. The shifting is great and is in no way neck-snapping. My favorite part of this tune is that it is designed for 93 octane, but leaves the factory features that adjust automatically for octane level. In the winter, I have been running 87 with no issues. I do notice the decreased power at that octane, but it is still far better than stock. I am running at 16mpg on a mixed commute with this as well.
