So...
Mods That Increase Gas Mileage:
1. Intake
2. Exhaust
3. Cams
4. Rockers

What else? I think it would be a good resource to get a list here, maybe in techinfo. Any other mods you guys can think of?

1 Regularly using fuel injector cleaner.

2 Having a big wallet (won't worry about MPG)

Mods That Increase Gas Mileage:
1. Intake (Includes Air Intake, Larger Throttle Body, Ported Blower, Ported Intake Manifold)
2. Exhaust (All of it!!!)
3. Cams
4. Rockers
5. Custom PCM'* with better fuel tables

There are many more things, but those are the simplest. The thing that most determines your gas mileage is your right foot![/quote]

Very ture, it'* all about my right foot!
It'* HEAVY! what can I say

Just went to court for 75 in 55 on the higway, was about 1 am one friday night coming home with the girl from the bar, officer said he saw me going much faster but didn't get me on radar untill I slowed down. Oh well, nice ILL state trooper, didn't hassel me at all. Went to traffic court with my new favorite lawer and got it thrown out! Oh ya. This guy even got my case to be first up, it was dismissed before I even got infront of the judge. In and out in 5minutes, best ticket experience yet. What a guy. $200 well spent. Don't let anyone tell you the courts aren't corrupt! He also told me to NEVER take the breathalizer, even if you get arreseted for something, we'll get it thrown out in court. Anybody in Chicago land need a traffic lawer, I got the guy for you!

I just got 21.1 on my fill up yesterday, I'm thinking of resetting my PCM now, or after an ADTR hits my door.

Most of my driving in this small town is city driving at speeds of 40 mph....OK with short blasts to 60 mph....
We only have 5 stop lights in town and you can get away with stopping at only 2 most of the time.
20 mi of road north until we hit the end of highway 101 that starts down at the Mexican border and 20 mi of road south until we have to take a Ferry to Vancouver. Of course I know every inch like the back of my hand. The best part about it is that there are no police except in town.....they hover around the local donut shop.
I always reset my DIC on every fill-up and have never seen better than 16 mpg average. Lots of short trips of 10 -15 minutes.
Once it'* warm it will get 26 mpg and on a few longer highway trips has been up close to 28 mpg doing 85 mph.
