my friend has just got a fiesta zetec s . he was just wanting to know what kind of chip to get e.g were .price simply use to increase the bhp .

 

you can bluefin the Zetec-S but you wont see more then 5bhp gain so its not really worth the money. its difficult to get any more power from a ZS without going for proper engine work.

Best get a cone air filter and stainless exhaust and just enjoy the noise the ZS makes
