#1 of 24 Chevy trucks and suv's

Will GM step up and help out the the consumer who owns a truck or suv? They always talk about consumer loyalty, how about loyalty to the consumer. GM needs to step up and create a fix for our engines to increase fuel mileage. This fix, which I'm sure GM already has developed for future vehicles, would go along way in the PR department. It would also keep loyal GM owners from feeling abandoned and keep them buying GM. It might also help save jobs. Any thought on this.

I think you're dreaming.
Chevy trucks and SUV already have best in class mileage. With gas prices at an all time high and SUV/truck sales down the tubes you can bet that GM would've introduced any significant mileage increase miracle if they had one rather than closing down 4 plants.

Asking for a "fix" implies that something is actually wrong. These are full-size trucks. They require sufficient power to move them and their loads. That comes at the expense of fuel economy unless you have a diesel. Nothing will make these trucks "mileage kings".

#4 of 24 MAP SENOR adjustment to improve gas milage
Jun 10, 2008 (10:20 pm)
I have a 95 GMC pick-up with a 305 engine. I just now put in a modification to run my truck on HYDROGEN (water). I improved my gas milage from 18.2 to 22.4. How can I adjust the MAP SENSOR so I am getting less gas (doing this will improve my gas milage even more). The HYDROGEN combined with the gas almost double the octane so I now need less gas to the engine. Is there a MAP SENSOR that you can adjust? I need to fool the computer so I can tell it that the engine is running to rich.

If it has a screen, remove it. That will cause a lean condition.

What if it does not have a screen. Any other suggestions? Thanks

If it doesn't have a screen there's not much you can do with it since all it does is measure the volume and temperature of the incoming air.
#8 of 24 Any bolt on MPG improvements for 2004 chevy2500
Jun 26, 2008 (6:19 am)
I own a 2004 chevy 2500 with a 6.0L and a 3.73 axle ratio. I am wondering if anyone as a similiar truck or same size motor that has put any bolt on's such as a air intake kit, fuel catalyst system, computer programmer, throttle body spacer, or anything else that has gotten any real world MPG improvements. I read about alot of the products that "SAY" they give you MPG increases. I wondering if anybody as any experiences with the products?

The items that you've listed will do two things. Increase in cab noise and lighten your wallet. The manufacturer would've done all of the above in their quest for bragging rights in increased mpg if they beleived it would've helped.

i have a 2003 silverado 4x4 with a 5.3. my question is that i feel the mileage is poor compared to what i have heard other trucks are getting. the best hwy i've seen has been 15.5 hwy. i put a volant cold air intake, a torque spacer and a magnaflow exhaust system all with claims of mileage improvements. i have driven this vehicle at a pace to try to get mileage but have not seen any gain. any ideas?
