Throttle hang?

On all the stock tunes I've played with throttle hang only happens when the engine is reved past 3200 and the throttle pedal is fully released. Most only realize throttle hang is an issue at the end of a run when sled pulling. The engine is seldom reved past 3k on the street because mildly modded stock tunes don't make power up there.
