Helps improve fuel mileage.
yes, but they require that you only run Premium fuel. The savings on mileage is offset by the extra cost of the fuel, and its not worth it.
If you have not done so, replace the plugs, plug wires, air filter, and fuel filter. Also replace all under hood vacuum lines.

Install a hydrogen fuel cell. Google fuel cell llc. I noticed their first cell produce is for the N14
Keeping up with scheduled maintenance, better driving habits... a lot's been done since ACERT went into effect in the early 2000s which has impaired fuel mileage... EGRs decreased fuel mileage, SCR/DPF/DEF decreases fuel mileage, 2007 introduced Ultra Low Sulphur Diesel - which is a less efficient fuel than the previous low sulphur diese - all in the name of emissions. Turbocharging remains the best option to improve diesel efficiency.
no, they just mean that the engine has a supply of hydrogen to run on rather than any other fuel
A Chevy Avalanche uses standard 87 octane fuel. Higher grade fuel will not result in improve mileage or performance.
High performance exhausts can have a small, yet statistically insignificant, impact on fuel efficiency. They tend to be installed for a differenct exhaust sound or improved power, not improved fuel mileage.
programer. there are many out there that offer power and fuel economy. banks and superchips are just a couple
