BIGGEST PILE EVER!!
Just Kidding, trading trucks wont work on the new one. I loved it, put it on my 05 when it had 11 miles on it and have had no problems at all. I never ran it on level 5 much, it was pretty crazy, lots of smoke!! I had it in there just because I could. Make sure you have them set the trans up. There is a difference on the EJD3000AWAM's for transmission settings and yes you will notice the difference. They come default with Auto and 3:73 (3:55??) gears from the factory. If you have a manual or 4:10's you arent getting what you paid for!!!!!!!!!!!!!!!!
