I've started trying to improve my 2.0l zetec (mk1) and I've been looking at the ecu modding options like powerchips and superchips, both claim to offer up to a 10% increase in BHP and torque for around £220. This sounds a little too good to be true, I'm sure there must be a downside or everyone would do it especially since an induction kit or sports exhaust wouldn't give you 10% and they can cost more. I would be really interested to hear the opinions of anyone who has done this to any car.
Thanks guys.
