I have a 2004 2wd 3.7L V6 dakota and i was wondering about this Jet PCM thing...any good? anyone with any experience using it? can you use it to reprogram your computer for bigger tires?

 

I wouldn't waste the money. Its pretty much a paperweight. I've never talked to anyone that had anything good to say about them. I would say go with Superchips but unfortunately the don't offer one for you motor at the time. They have said that their isn't much interest for that application so maybe emailing them about it would show them that there is some interest out there. I know some people on other sites with your motor have done the same. Good luck

 

is there any way for me to calibrate my computer for bigger tires other than that? i don't want to mess up my odometer or speedometer.

 

Not that I know of. YOu would probably have to go to a garage or the stealership. [:@]
