I can't imagine anyone manufacturing a chip that would reduce horsepower

I don't think it would improve your gas mileage even if you could reduce HP. You would just end up stomping on it more to try to get the same performance, and probably end up worse. :dunno:

I wouldn't let anyone muck with it anyhow.

One small, easy tip that I always recommend is to be anal about checking the air in your tires. I find that keeping mine on the high side helps improve my gas mileage.

I'll second that. Any driving activity that reduces brake dust will also improve mileage

You are welcome. Another thing to try is to try to coast to a stop instead of braking at the end. If you see red, ease of the pedal and your car will gradually lose speed.

Whenever you try these things, make sure you are not being tailgated by an aggressive driver to prevent rear-ends. If you are, step down and leave him in the dust :bigpimp:. You can always coast on the next red light!
