Hey guys, does anyone have one of these? It is a chip that is basically a transistor that goes on your air temperature sensor and is suppose to fake it out. Meaning telling the engine that you are getting ALOT colder air than you are really getting. I have one on my car now, but I really do not know if it is doing anything, except turning on the check engine light. I am going to the track on Tuesday and trying a few runs with it and a few without it. But I was just curious if you guys believe in these things?

I was curious about those to but now i got the SCT tune i am not gonna mess with it. What else u have done to your car to get those numbers? Unless u dont have the orignal motor it in and have a 4v or something.

The original owner put headers, new heads, and a bunch of other stuff to it that I do not even know about. I'm the 3rd owner, by the way. It dynoed out at 303.9, so I'll say 304...

All it does is make it detonate on hot days.

Its a waste.
