anyone know if they are any good and what they all do? and any good ones?

 

I read a lot about these and I found that they are just resistors that trick your computer. But eventually the computer figures it out. Me and A buddy of mine tried the power chip air/feul chip and did gain about 5mpg and better pull through gears. Hope that helps

 

they don't exist... don't bother.. what you'll find out there are scams.

 

i got the unichip bro and well i seen that they also come with turbonetics instead of the AEM one. i have seen alot of threads on here with both good and bad opinions but at the end wat matters is wat u think of it. i decided to give a try and if it dont work then i could always sell it. but its up to u bro.

 

Unichip, greddy emange, aem fic. Take ur pic....

Go boost or its not worth it
