Performance chips good for better gas mileage?

It's wondering if a cheap performance computer chip type thingy has ever helped anyone out there on gas mileage or any other beneficial aspects.

if they're good for gas mileage, its only because of the weight reduction observed from your lighter wallet.

My Superchips programmer did nothing for my mileage (it was advertised to improve mileage), but the performance gains (chiefly improved function of the auto transmission) was worth the price for me. Others on this forum will agree.

performance chips do nothing for older vehicles that are still a machanical eletric throttle bodies and where the ECM system only monitors the fuel to air ratio, but some would argue that with the newer fully computer controlled vehicles the chips work because everything from timing to the fuel/air ratio is controlled by the ECM and so in theory the chip and change some things to get better performance.
