Chips

[metz]

I am curious if these chips are so great (increased hp, mpg, etc...) why don't they come programmed like that from the factory? I mean why wouldn’t Ford want you to have as much hp as possible or the best possible fuel economy? There must be a catch somewhere. What do you give up when you put a chip like that in, do you give up engine life?

Thanks

The stock truck is "set" for the best all around towing and drivability. Since people are going to tow and drive it around, they cant have just a high horsepower truck. They make it where its in a happy medium

exactly. They are meant to tow so if Ford gave the trucks high horsepower programming, it would make egts super high etc.

So when someone has it on high hp setting how do they keep the egt down?

They watch it and dont tow with it. Most people get tunes that they can tow with and tunes that they can just drive with.

Seems kind of risky to me. It seems to me that the stock setting would be the best setting unless you are really trying to race or something. The chip must tell the computer to dump more fuel to get more hp. But what does the chip do to make the engine more fuel efficient. Do you give up hp for mileage?

no,
more power=less strain on the engine=less to make it go
and some chips like dp or tw tune your tranny.
also the trucks are probalt down tuned to meet emissions

Any time you make more power you are putting more twisting force (torque) through the recipricating and rotating assembly.

But that said if you are making more power out of the same amount of fuel yes the motor will be more efficient, it will use a little less fuel to do the same work.

But some tunes like economy, will adjust injection timing, and shift points, making the most out of the fuel that is being injected and shifting at a lower rpm so you don't need to rev it out (inject more fuel) to get up to speed.

emmissons is a big factor. To pass can't show any black smoke.
