Just installed mine and so far it seems like it's gonna be fun.
The install took five minutes just like everyone says. I unlocked my truck (remote start fob) and then left it for about 15 minutes with the fob in the house. The hardest part was squeezing my fat ass under the dash. Also, it helps to have a light handy. My phone was plenty.
Here are a few quotes from some texts I sent to my brother who is a total gear head.
Me: "Dude, I just installed the Pedal Commander and it makes the truck FUN to drive!!! It wants to break loose on a simple left turn from a light. I've only gone to level 2 (Sport p4). I'm a little afraid of "race" levels. "
Him: "Is it really that much faster?"
Me: "It's not that it's faster really, it's that it responds so much more quickly that you're going fast before you know it. I was looking down and seeing 60+ on Brookhurst in only a few seconds. It actually feels like an older big block instead of the "gotta nail it to really feel it" 5.7 Hemi."
So that's my review in a nutshell.
