I am just wondering if this company is legit or not?

Sounds good, but cheap, so that'* the only question that needs answering.

that is crap. It just makes you run rich.

yeah, there'* a lot of variants of these around. basically, it'* a resistor (but man, do they charge a lot for a .10 resistor!) that makes your IAT think you're getting colder air.

you're not, and the car figures it out pretty quick. and then your 50 dollar ten cent resistor is worthless, as the PCM decides to make things right again.

but there sure are a lot of people selling them under different names, aren't there?

maybe there aught to be a techinfo on what not to buy for ur car
