Quick question?

I have a 2003 Dodge Dakota QC 2wd 4.7L
I am looking at getting a Superchips programmer and I know there are three models for my truck.
3715, 3815, and 3865
What is the difference between the three other than the 3865 being the newest and most expensive?? Are they tuning options that dramatically different to justify spending a heck of a lot more money??

Since my truck is already 6 years old, I don't see why Superchips would make any new changes to the tuning specs.

Thanks

 

the newer ones are updateable so if your just looking for a basic tune the 3715 is the same tune as the other ones just cheaper and if something better does come out you cant upgrade at least thats how it seems from what i've read

 

I plan on getting the 3715 since on ebay they are only around $130 - $150 these days. Just make sure its vin unlocked.

 

yeah it doesn't matter too much for the 4.7, i think the 5.9 saw some noticable gains from the 3715 to the 3865 but ours didn't change at all
