Has anyone tried this chip and would they recommend it. Their web site states just simple plug in engine bay (ECM?). HP and gas milage gains. Money back guarantee.

 

I can't believe that company is advertising and selling that kit as they have certainly sunk to another level, 60HP and 4-7 more mpg. Having said that, I would venture to say that it is nothing more than a resistor attached to the IAT to provide feedback to the computer that would indicate a lower air intake temp and therefore a richer mixture and timing change would be generated.
If you Google and read some results there was a fellow that installed one on his CTS-V and with sophisticated equipment monitored the before and after and his results where no changes.

Save your money.

 

 

Yeah, those chips are bogus. Didn't someone on AZ get one of those chips, break it apart, and post pictures of the nothing inside?
