Would my truck benefit from a programmer?

Programmers DO make a difference all right! The Gryphon made the shifts much "quicker" and more precise (no "delay" in downshifting when passing), and, my fuel economy went up by about 2 mpgs. I would hate to drive the truck without it.

x2 I can't stand taking my truck into the dealer without the programmer on it. Feels like a dead horse on the way there.
