its not a mod-chip or and IC(integrated ciruit) its a resister in a fancy plastic box. it is not worth 2 cents literally. If you hook it up, it will make your car think the air is 55 degrees and mess up your engine.

Also, the guy selling this junk lies and leaves insulting feedback if you have the decency to post the truth. Just look at the lies this jerk posts to people who don't give in to his strong arm tactics.

use google to find other horror stories about this product.

ALWAYS research BEFORE you buy.

If you HAVE been ripped off and payed with paypal, you can dispute the charge because the product is not as described. a resister is not a chip.

Leave negative feedback and don't give in to his threats. He can't do anything to you.
