No. You will see no power difference between a 2011 truck with 15+ turbo and pump than you would see with a 2015. Any difference there would be tune related.
Where you see the difference is when you run a stroker pump or dual fuelers with a bigger turbo setup and can only see 700 HP on an 11-14 truck and on a 15+ you might get 740HP. (Numbers for illustration purposes only)
