I remember those simple IAT 'performance' gimmicks that just told the ECM the air was denser (resistor), so it dumped more fuel into the cylinders. The newer ones were actually a 'chip' (usually mostly only using one or two paths with a few added useless components making it look 'computer-like'). Old saying, there is a sucker born every minute, and still holds true today (which motivates scams or fraud endlessly). No telling what this 'company' does but I would suggest you do a lot more research BEFORE sending $ (try contacting them by email) and find out what they provide and what they are charging. Who knows, maybe they do 'reprogram' the air/fuel maps... Good luck
