mpg/full tank

What's the average mpg off a full tank of gas u vortex 96_2000

34 gallon tank and I am averaging just at 13.8 to 14.5 from No. Utah to So. Cal lots of mountains to go through in Utah killing MPG for early part of trip..

Got 321 off full tank think im at 11 mpg

i get 9.5 empty, and 9.5 towing my 24ft tothe desert with our tuys in it. i seriously need an ecu reprogram

WTH????? I go almost 375 miles and I'm looking for a station, I usually have about a 1/4 left in the tank and that is with a 454 rebuilt to a 502 chipped, something ain't right with your trucks!!

california smog... these ecus are clogged up pretty bad.. i need to get my emissions delete, my cats are partially clogged i think. and re program the fuel and ignition curves.

im so thankful that the state of florida finally did away with the emissions testing every year! i can run pretty much whatever i like on the street

Domer Cali Smog is defintiely true glad I don't live there anymore my first 20 years of life were enough LOL!!! visiting is about all I can take now!!! an ECU reprogram couldn't hurt.

My truck is registerd in Oregon.. I built a monster intake for it, and i have an exhaust on it, with a the AIR deleted. But the CEL is killing my mileage right now.. wporking on doing a tune, deleting all emissions, cats, 2nd O2's, and reprogramming for towing. should make a difference..

A few, unrelated questions...

How do you register your truck in OR? You got an address up there or something?

I guess that means you run Oregon plates, then? What happens if you get pulled over? Seeing as how you have to register your truck in CA like 30 days after you move in, you could run into a dick Cop who could make your life hell.

My parents live in Vancouver, WA. Costs my Old Man something like $50 for 5 years to register his Crew Cab Square up there and no emissions testing. If I could get away with registering it with them, I'd do it in a heartbeat.
