Pedal Commander vs aftermarket tune?

2016 Colorado 3.6
Has anyone here heard of or used the "Pedal Commander"?
I did a search on throttle response and came up with this item. it gets wired in series with the cable that is attached to the throttle pedal. It has 4 different modes and 4 different adjustments for each mode. Doesn't void the warranty and no flashing computer. (I think) I've never done an aftermarket "tune" and this product looks real easy to install and as it seems, you can adjust different modes by pressing buttons on the device mounted inside your vehicle. It's $299 for the 3.6.
I have noticed that some of the "tunes" require higher octane. I don't know if this is a factor for this item.
Any thoughts?

I have never used one, but here's what I think I know about it:

Your pedal does not have a cable. It's an electronic rheostat that's wired through the ECU, and then to the an electric motor on the throttle body. It sound hokey, but most cars and trucks are built this way now. Even Harley does it, and you know how far behind the technology curve they are.

With this set up, your foot does not control the throttle, the ECU does. The manufacturer programs the throttle response according to their needs. Torque management to soften launches and save the drive line, slower throttle response for better city mileage, etc.

The Pedal Commander plugs into the top of your pedal, and then the factory plug goes in to the PC. It modifies the signal that gets sent to the ECU. It doesn't modify the ECU or any programming. It's not a "Tune" in the traditional sense. So, in theory, it won't void the factory warranty - but it might, so be careful.

Companies that actually provide a tune to modify the ECU, will usually make changes to the throttle maps. If you plan on adding a real tune at some point, the Pedal Commander will become obsolete, and you'll probably have to remove it.

So I'm wondering if this is another way to correct the bad throttle response that we sometimes get with our 3.6?
They do claim it won't void our warranty.

Oh wait...what I should be wondering is...will it prevent the transmission from downshifting too many gears and launching the truck like a wild bronco?

Good question, I have always felt that the accelerator and trans were not completely synced up. I had my engine and trans computers reflashed at the dealership and 98% of my problems went away. I've wondered about finding something that help would accelerator be more responsive. I hope someone gives this a try and some feedback on it works.

I'm guessing....not.

And only because the information from the Pedal Commander is considered INPUT to the computer. The computer takes that INPUT and adjusts it based on the program (and probably a gazillion other pieces of INPUT).

If someone is willing to spend the $ and try it...go for it.

And actually - the Pedal commander might be a way to calibrate the pedal. My last truck, you could perform a pedal calibration (Pedal Throw) via a few steps. Say for instance, you could set the overall THROW (0-full throttle) in half the distance of the actual mechanical throw. If your foot was halfway down on the pedal, you'd actually get FULL throttle instead of needing to actually push the whole way down.

My wife's had a slew of BMW cars that came with their 3L TT motor, and being known for having a 'slowwwww' pedal, I've installed these types of devices on some of 'em
It works because you're dealing with a throttle by wire(most common now days), and simply gives you a 'quicker' calibration than what comes stock.
The ones I've installed go underneath the pedal, and literally take a whopping 2 mins to install.
They've all worked as advertised too(no throttle 'lag')
