thats what it looks like to me too. i used one of the ones from ebay when running a autoX one day.....not serious just a local event......i forgot to take it out and ran rich way too long. not only did it affect fuel mileage, but i have 2 clogged precats now, which i have to gut. i would stay away from any of that "easy install" stuff. if its that easy, probably nothin but trouble.
I've used the Surge Performance Chip. I did feel a little power only at night time. But it's tricking your ECU thinking your computer is running cold and needs more fuel. I couldn't pass smog and the CEL would come on non stop. It was connected to the IAT Sensor. It's a COMPLETE WASTE OF MONEY...It caused more problems. I just found it it's the same Resistor(So-Called Performance Chip) is actually a LED/Neon Tube Light Adjuster Here's the Link To Prove It...Just Scroll Down You'll Know Why.
