Anybody have experience with the Diablosport i3 tuner on a 07-13 1500? I

I've been looking for a way to clear out the "dead" throttle space in my truck and make the shifts a little more reliable. The i3 tuner appears to do all of that and more for ~$400. Wondering if it is worth it.
I already have AFM disabled via a Range device but could also get rid of that with this as well.
Curious if anyone on Reddit is running a tune from them and what they've experienced

Legit question here....are you a bot or a real person who posted the same message to Reddit?
