Yes, fuel prices are high......The truth about fuel economy.

If you're talking about the estimated economy display in the overhead console, no, it will not be accurate after install (this is why people who buy aftermarket programming instantly tout that they went from 14 MPG to 675.3382 MPG).

Thats EXACTLY what my question was. Thanks for clarifing.


Ive never seen mine go to that extreme. 675MPG (LOL) , but when it says 15. 8 in town, or 19.5 on the highway average before, then after the chip install it goes to 16.5 in town and 20.4 on the highway......, I was just curious as to what effect the chip has on the trip computer.

Very, very well put, Cody.

Is it impossible to get better mileage with aftermarket tuning? No. It it reasonable to expect an increase? No. You just have to realize that if you want better fuel economy, even with aftermarket tuning, that you're STILL going to have to drive like you actually want good fuel economy. There are things that all aftermarket tuning companies do to help increase the efficiency of the engine. The automakers are responsible for selling a product that makes a specific amount of horsepower and remaining suited to taking on all kinds of driving/usage demands. They also are REQUIRED by a rip-off governmental agency called the EPA to meet certain guidelines for specific emissions. These emissions guidelines have a profound effect on what automakers can get away with in thier stock tuning. Basically, we in the aftermarket trade hydrocarbons for oxides of nitrogen. We can increase the combustion temperature and pressure to help with efficiency. This increases the amount of "Nox" emissions, but helps a little with hydrocarbons (which boils down to efficient fuel usage).
