You would definitely feel it if it were defueling. With a stock turbocharger and high pressure oil system, these trucks really fall flat on their face after 2500 RPM anyway.
If you get a mechanical pressure gauge and temporarily install it, you can see what the truck is actually doing.

If you do find it is de-fueling, you can buy a boost fooler. This one is plug-and-play easy installation and inexpensive.
