So I bought the pedal max too. I was impressed enough with the boost max that I wanted to try it. It works. It makes the throttle MUCH snappier in all modes. I'm not sure how much I like it though to be honest. It isn't making the truck faster or more powerful. It's just improving the throttle response. The response is crisp, but it also makes the truck a little jerky and you lose some of the fine low end throttle control. You'd have a terrible time with it doing a rock climb or blasting through a rutted out trail I would think. I also question if it's such a great idea in the snow. It's almost like it narrows the power band. I just installed it tonight. I need to drive it for awhile before I draw any conclusions.
