I have a new 2012 Outdoorsman with the Hemi. My best friend just bought a 2011 Crew GMC Z71 with a 5.3. We ran the trucks yesterday and we were pretty even. I wonder where my other 70 HP is? His truck is rated at 320 mine at 390. He has a 3.42 rear end and mine is a 3.92. I turned traction control off and put it in 5th gear. I will have to admit I was kinda disappointed. On trucks as equal as ours are I would think 70 horsepower would make a difference
I came home jumped on the internet ready to order the latest and greatest programmer to give my truck every benefit. It became clear there is none. I have defected from the GM camp myself where I have had a multitude of programmers on my trucks.
I find information here that says Chrysler has encrypted the software so that nobody can break the code. That does not make much sense to me. I understand that Chrysler is under pressure by the govt and cafe but why not make it easy for customers who want to turn off the MDS and increase horsepower at the cost of gas mileage can.
So I guess my big question is does anyone know why not?
