Do they work, or are they just bs???

 

Theyre BS.. Just a little resistor or module to make the car run rich a little.. After a while the PCM catches onto it anyway and corrects it.

 

Thanks for clearing that up. Glad i didn't spend my 76 bucks on that thing.

 

Wow you can almost buy a PCM tune for 76 dollars. But yes, these "chips" are nothing more than a gimmick.

 

I have the Hypertech power programmer III and it did great.. Changed the shift points to where i want to set them and remove the top end governor and adjusted the mixture for more power. I choose the option for running 93 octane for more power . I saw a big difference.,,,

 

What you have and what hes asking about are two different things.. What youre talking about is well known and very useful.

 

Price and link.. pm me if necessary.
I'd like to purchase one if ya have any info.
