Improving performance and gas mileage

[AaronSptTrck01]

All,
I'm going to be doing some mods to improve the performance and gas mileage on my 2001 4.0 4WD ST. What are some cheap mods that can be done? Planning to spend around 1000 dollars total.

What do you mean have the computer tuned?

Using an after marker program in the PCM; ie, a chip or a down loadable program.
