$69 chip?
Anybody tried the $69 chip advertised on this site? They claim some serious MPG gains. I don't care about any power gains, a 4.6 is going to be a gutless little snake in a full-size 4X4 anyway, but some help in the gas burning area would sure be welcome.

I need 4wd this winter, record snow and cold. Any 4wd will be as bad as this Ford, I think. Just clutching at straws to save some gas. Not gonna happen, maybe. About what I thought, thanks anyway. All those "chip" ads seem to be too good to be true.

It is basically a 4.7K ohm resistor that tricks the pcm into thinking the incoming air (IAC) is 10 degrees cooler than it really is and richens up the air/fuel ratio. Worth about $0.79.

The ad probably says... "up to" 4 mpg increase. You can also see "up to" 5 mpg increase if you train your right foot to accelerate slowly up to speed instead of launching from every start.

Have the instructions been translated ? Or are they still in Chinese ! Sounds like Snake Oil to me . If it tells the ecm it is colder , it will command more fuel . It may give a bit more power , but should use more fuel ,not less .
