I run the Edge Juice W/Attitude on my 6.0 Powerstroke and could not be happier. I know that's not what you are asking but, I figured I would chime in. My truck is a beast and real damn fast especially with the amount of lift and tires. I run that chip with Airaid intake, RBP straight 5"exhaust and it runs great. MPG sucks but, I don't care about that. With a stock height truck and a good setup, your MPG will shoot up for sure. Effeciency=HP and to a certain extent, HP=MPG. At least till you start getting crazy.
