Anyone have experience with these? Are they any good?
I have seen them for the 4.7 2003-2008.

Just wondering.....

 

havent really heard any good about jet modules...if anything at all...everyone would much rather have a tuner..much more tunability and alot more features...

 

ive heard of the jet chip frying pcm's.... read lots of posts on them and decided to steer clear of them. plus they are what $230. for double the price you can have a handheld with way more capability ( yes i know double is alot but its a great tool to have) if you just wait a little longer, they might have updates for the 08s..... i personally wouldnt risk it even if i read one post os a jet chip frying a pcm on a dodge but thats just me....

 

Jet chips get the thumbs down. Save yourself a lot of headaches and disappointment and get yourself a tuner.
