I will be getting a laptop and tunercat in about a week, i was jsut wondering what i should change in my PCM to get better gas milage, and a little more power from the mods listed below? thanks for any help!

 

First, spend about 6 months or so getting to know what every tables does in TC and how it could destroy your engine if you put the wrong values in. Then start making changes very slowly and logging after you do a reprogram to make sure everything is running ok. You'll be happy you did, because some of the things you can change can and will destroy your engine in the time it takes to upload a program.
