Anyone tried anything like this?

Has really good reviews on ones for other vehicles, but obviously nothing for the sky.
What does everyone think? any reason that this might give better response, better low end, any gains at all?

With keeping in mind, I have an open magnaflow exhaust and a ddmworks CAI on the 2.4 base.

Plug in learning tune from amazon

It is a spoofer. It modifies signals going to and/or coming from the ECM to "trick" it into running differently. Unfortunately you have no idea how it is doing it or how it is affecting how the car runs. You may feel "more power" but without knowing how it is doing it, it could be harmful to the car.

I'd run away from that like the plague.

The reason why it worked is because the Intake Air Temperature table in the ECM was a base timing modifier table. Meaning it would add or subtract timing based on temp. Now the OEM values basically only would pull timing if air temps were over 100 degrees. With our "happy knob" (That's what it was called) you would change the values in that table so depending on what you had it set to, you could adjust how much timing you were adding to or subtracting from the base timing table.

This device in the video is nothing like that happy knob in the way it works, only that it is intercepting the intake air temp sensor signal.
