I saw some of these chips on eBay starting at $6.99, another at $59.99, and others up (new from dealer). I asked all of them to send me technical data proving the increase in HP that they claim (dyno or other), and they al refused to send data, which only leads me to believe the claims are a little (so as to not say COMPLETELY!) bogus...
As they say... If it sounds too good to be true, it probably is. But having said that, at $6.99 you cant really go wrong.
