No matter what he does with the throttle he gets no power/boost. icp? It has 4.10 gears and his 3.55 truck pulls better. The truck is bone stock.

Are you saying that no matter where the pedal is pushed to the engine remains at idle or are you trying to convey something else?

Oh OK. Is the engine light on? Are there any codes? What is the fuel pressure at? Do you hear the turbo spooling? Is there any kind of smoke and what color when attempting to throttle up? Does it sound like it is bogging down when you give it throttle?

Is this only when going from a stop, or is it even when already rolling (15+mph)?
Have you checked the air filter? It's easily overlooked and, if plugged, will give poor performance across all pedal/RPM range.
