I'd like to know if a anyone is running a TRUCK EDITION performance module on their 6.7l 2011 ram? I have one and I am not sure if it's going to hurt my engine. I just want to run it to get fuel mileage, not for pulling. Truck has plenty of power for pulling 14,000# GVW 5th wheel and I get about 10 to 11 MPG pulling. Note pulling 13/14mpg.
