None.
These engines just don't have the tuneability of newer trucks.
Tuners can help with transmission shift points and firmness, and can allow to adjust tire size.
If you go with a 93 octane tune with a good trans program, it can add a little more pep, but again, nothing like the '04+ motors. Plus you have the 4.6, which responds even less to a tune.

Yep. I wanted a tuner only so I could get my speedo to be correct for my larger tires, but instead of a few hundred for a tuner, I've been contemplating spending $2300 on gears... for over a year now.
