fuel saving chips??

[gerry]

Hi all,

I was looking at after market chips for my mazda 3 2008, and I found this on ebay:
http://www.ebay.ca/itm/PERFORMANCE-CHIP-FUEL-GAS-MONEY-SAVER-MAZDA-3-5-6-MIATA-CX7-9-MILLENIA-PROTEGE-/310878161283?pt=Motors_Car_Truck_Parts_Accessories&hash=item4861c84983&vxp=mtr&_uhb=1

It claims more HP, and better fuel efficiency...

Has anyone tried this? I am only interested in better fuel efficiency. Does it really work, without damaging the engine?

Thanks

Gerry

Look into a hypertech or dynotronics tune if you want to tune your car.
