Re: JET Performance Module ???
There are many pros & cons on this one at most Dak forums, It does seem a lot of people think it works a lot better on the 3.7L than the 4.7L which I guess is a good thing for us. But then dan the fastman thinks the ECU compensates for the gains over time . I have thought about getting a stage 1 but thats a lot of $ for just short term gains so I don't know just my 2 cents.
