Before you chaps roast me to the ground:

1) This is probably to good be true.
2) Any performance mod with the word Vortex in it is typically a scam.
3) I am seeking constructive feedback only from those with firsthand knowledge of the product.

HOWEVER: This is what they claim $59 will get you:
- Up to +35 Horsepower increase
- Up to +40 ft/Lbs Torque increase
- Up to +9 MPG Increase

Here's the link.

 

I think it's VERTEX.

 

Looks like one of the scam performance chips that just alters the coolant temp signal to give more fuel. A programmer that can change the tune will not be $59 sadly.

 

Key words: UP TO. Meaning: 0 improvement up to whatever we feel like claiming.
