i have a 99 V6, and was looking to add one of the stage one Jet power control modulators. Just was wondering if any one had heard anything about them, or if they were any good?? not look for any massive horsepower gains from it or anything, but maybe a few extra. Just wanted to know if it was worth the time.
i have heard some people say their not good for the engine as well...

 

there was one installed in my grand prix GTP when I bought it, threw some maf sensor codes with it and ran pretty poorly overall, removed it, codes went away and ran much better, just my experience.
