I have a 2010 Armada. A guy at work had a Titan and has the Superchips Cortex 4950 that he ran on the truck. According to the box it only goes through 2009. However online it says it goes through 2010. Does anybody have experience with this chip? I am assuming when it was made the newest model was the 2009 so that’s why it says that. But does anybody know for certain? Do I need to update it to get the 2010 tuning or should it just plug and play? I am not looking for extra power I am plenty happy with the stock power. I am looking for increase MPG. I will only be running the economy tune. I know it might not be much of an improvement but even 1 mpg is worth it to me as he only want $50 for it. Any help or experience with this tuner would be much appreciated.
