If it's a 4x4 I would put a lift and 33's or 35's on it. With 35's, 2,000rpm would be about 67mph. 2,500rpm should be about 84mph. Running the truck at 2500rpm all the time won't really hurt it, it's just annoyingly loud.

Back out the circled screw n stick it in your glove box. Also the throttle linkage at the pump and the return spring switch holes for a more crisp throttle response you will have to readjust the rod but it's worth the 2 minutes of work.

Move your throttle towards the pump head. The screw it hits before the head is the high idle screw. You want to let the throttle hit the head.
