which chips\modules are you talking about? post a link to one. If its the ebay ones that claim more power and better fuel economy then no, they dont work. Its a disaster waiting to happen.
To get the best out of your vehicle, make sure everything is running in proper condition. Give it a full tune up, if you havent done so recently. Oil change, spark plugs, fuel filter, compression test, and a tune to check your a/f, etc... If everything is already runnign perfectly, you can add an exhaust, cai, and a handlheld tune. This might net you 1 or 2 more MPGs.
