Jet Performance Products "Xcellerator"

I recently purchased and installed the Xcellerator on my 2018 Tacoma TRD.
I had a few issues with the product. I installed the unit and it didn't work, I got an error code the collision sensor was disabled. I returned the unit and received a new one.
The install is simple and takes about 30 minutes at the most. Unhook the battery, pull the harness off the gas pedal and attach the Xcellerator. Zip tie or Velcro the small unit up away from the heating duct. Velcro the remote (to change settings) somewhere you prefer where you can see it and reach for it. The unit has 5 settings: Stage 0: Stock (OEM) | Stage 1: Semi Sport | Stage 2: Sport | Stage 3: Ultra Sport Stage 4: Track | Stage 5: Valet | Stage 6: Security.

The unit takes all lag and transmission gear "searching" out of it. I absolutely love it. I highly recommend it.

I attached the installation instructions.

 

What's the difference between this and the Pedal commander and OVTune

 

I have not tried out the other products listed but I can say the OV Tune seems to be in the $600 range and the Xcellerator is $299. I am completely satisfied with it. It makes the truck much more enjoyable to drive.
