Jet Stage 2 Module

[~chipsahoy~]

This thing came on my car when I bought it. I have read mixed reviews about it, so here I am getting more. What are everyones thoughts on this item? I am thinking of getting a custom tuned PCM, which from my understanding would be far better than the JS2.
Anyone have any ideas on what the JS2 is actually supposed to help as far as performance? I have not researched it much as I have much higher priorities on my list right now. Any help on the matter would be greatly appreciated. Thanks.

The thing about the jet chips is they are set to a basic set of performance peramiters. Not necassary the ones you have done to your car so they may help but a dyno tune would be the best followed by a tuning company (pcmforless for instance). That way you can tune the pcm for the specific mods you've done. Good luck.
