You can just reset your ecu by unhooking the negative terminal on your battery and then hooking it back on and then start your car back up and let it sit for about 7-10 minutes with out touching the throttle so the computer can re-adjust. I did this a while back and I didn't really notice any change in how my car felt.

But I'm sure it never hurts to try?? Try it and see if you get better gas mileage. I've heard of some people getting better gas mileage after doing this? Who knows, it can't hurt ya though.
