It's crap. While I can't comment on this specific unit, I have seen many like it. Ebay is notorious for the $19.99 20+hp performance chip. Notice how they don't explain what it does? Only how it plugs in and wont harm your engine. Basically what these "performance chips" do is piggy-back your MAF and makes the computer think the engine is taking in colder air than it is. Thus hopefully allowing full ignition timing. I have seen countless units tested and fail.The theories on making horsepower have not changed since the development of the combustion engine. They only got trickier with the advancement of computers. These types of units are complete junk, marketed to those uneducated about engine computers and performance parts (not an insult to anyone) or those with the wishfull thinking mentality. Stay away from garbage like this.
