Thanks for the help guys!

@Xist: Does the the air/fuel mixture constantly changing mean the RPMs will constantly change, even 4%? I usually shift into neutral, long before the UG. I have no idea if I have DFCO, but I haven't seen the 999.9 number, so I'm guessing I don't have it. I would like to know if accelerating hard or soft is better for my vehicle, but again gauge jumps all over the place, so it is difficult (sometimes only a few MPG jump, sometimes from 30's to mid 100's). I'll look into calibrating it properly tomorrow. I very rarely use the A/C, so at this point it is only vampire energy from the belt, so a 30% increase probably won't happen. Maybe one day, I'll just lose the belt for the A/C, PS, alt, etc. and see where it gets me. I'll try it for a tank and see what happens. I just want to lower GPH, not the actual RPMs of the engine. I would like to do a kill switch, but for an automatic? Wouldn't that be hard on the starter, having to restart the car constantly?
On a side note, when I first joined this site, I had all the time in the world, so I've definitely seen the arguments and I know exactly which buttons to *not* press!

@gealii: I like the idea for the UG not going off, but I would prefer it to just be a delayed off, so when I park I can still look at it and make any necessary changes.

@vskid3: Thanks, good to know my idle throttle is in "range". I definitely don't want it to start at 0. Do you think taller tires (like 70 vs. 65) would help make the speedometer and UG more similar or is that a different issue?

Ahhh, another long post! Just so many questions!...
