you got an 03 and up truck? DBW throttle body will do that. In my moms 04 yukon I can stomp the gas and let off quick and the tach will barely move..

Drive By Wire throttle body. It's electrical, giving it a bit of a delay.

Throttle response can be modified in the tune if necessary for the electronic throttle bodies.
