Fuel Saver?hp Chip

[burg226]

Hey, I'm looking into ordering one of these chips for my 2002 Sierra Z71 with the 5.3L. I'm not looking for HP/Torque gain (although i'll take it) but i would like to improve the gas mileage. I already drive slower and do mostly highway driving at 60mph and am getting 610+km (380+ miles) per tank. Has anyone tried one of these gas saving chips or something like it. Your opinion would be greatly appreciated. Here is a few ebay links to the chips i am considering...

Do a search and you'll find out why I am laughing.

NOOOOOOOOOOO, it would be cheaper for you to remove your bed, spare tire, rear bumper, passenger seat(s) and anything else that you dont use on a daily basis than put something like this on

Its a scam. It is basically a resistor that "tricks" your computer into thinking its colder than it is, thereby supposedly burning the fuel better and saving gas. It doesn't work. At all. And it probably voids any and all warranties you have. Including any on your tires. That is how bad it is.

I like how it says "fits vehicles from 1996 to 2008" , its a pure rip off.

you get 610kms to a tank!?!

 

jesus...i'm lucky if i break over 500..and i don't romp on it..i take off slow from stops and everything

I can get about that...only in miles.

 

I've found, in our Impala at least, that I get better gas mileage if I don't accelerate slowly. Works for me, cause its hard to keep off the gas!

I get about 600 km per tank as well (highway driving, 115 to 120 km/h or 72 to 75 mph) . I do have a wait4me tune in it biased to the mileage side. Unfortunately, I put that in almost as soon as I got the truck so i have nothing to compare against.

On my 06 4X4 Ext. Cab short box, 3:42 rear end;

 

My personal best is 742km(~461 miles) on a tank. It was about 23.8mpg on that trip. All highway, cruise set at 100km/h.

 

Most of the time, I get about 20mpg.

 

Not bad for a full size 4X4 p/u.

Considering the pressure auto makers are getting to get better fuel mileage, and the issues they have trying to deploy large fleets of gas guzzling monsters (I'm totally on board with this!), if they could get 10MPG from a $8 part, they'd be all over it.

 

Problem with MPG is trucks are giant, heavy bricks. And, due to physics, the rate of HP required (which is direcly related to MPG) is something like a 2x increase of speed needs a 4x increase in HP. Thats why cruising at 55MPH can get you the rated MPG, but you're no where near those figures at 65-70MPH.
