Has anyone ever tried one of these or know anything about them good or bad? Supposed 20hp gain and 30-45 ft lbs or torque

Thanks

 

its a scam

 

usually those scams are resistors that fool your motor into think its getting colder air then it really is, theres some truth to it but its really not a good idea. this device claims to not be a resistor or an ECU piggyback so im not positive what it is. but judging by the fact that he has it available for almost any make/model makes me think its a resistor in a nice package.
