Wow. Thanks so much Zef for the info so far.

Can you tune your VE and MAF tables for mileage, then tune your WOT fueling separately so you still get max performance? Or does it have to be a performance tune vs a mileage tune?

Is this a program I can download?

Also, allow the TCC to lockup earlier at light throttle, but unlock earlier at heavy throttle. Reason for this is that you use more gas by letting the car "lug" than you do making it unlock and downshift. I also set the supercharger to not come in till 30% throttle. Leave PE stock, or somewhere in there. Change my cold start fueling because that seems to be a really rich area.
I would like to change the cold start fueling too. One other thing I had in mind is changing my TCC lockup so it can come on at ~25MPH instead of ~30MPH. I drive on base a lot and most areas on base the speed limit is 25MPH so I get crappy mileage not being able to hit lockup.

I don't normally drive a whole lot during the week, but during the weekends I like to get the car out (even if I have to go out for no reason) to keep in in good shape from the relatively shorter trips and low speeds during the week. Plus some WOT runs on occasion to keep it as clean as possible between cleaner treatments.
