What you know about them?

 

They're junk, don't bother.

 

if you believe that those ebay chips work then paypal me $50 and i will cast a magical spell over the internet to your truck that will make it faster.

 

dont worry i aint buying them my buddy has a dakota and i just asked for him that all. ill see if he wants to paypal you 50 though

 

all they are is a resister that plugs into the iat sensor i had one i made and i notice a little diffrence but if you want to try it use a ohm meter and get the resistance off your iat sensor and find the according resister and plug into the connector that simple you can get the resister at radio shack
