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.

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. |

| 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. | |

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?
