Contour Enthusiasts Group Archives Forums Modifications Zetec Performance chip hp and torque gain

I agree but dyno tuned and what you call "off the shelf" tuning is usually just a difference of 1-2hp.

Not worth it to me to pay a dyno operator $150 an hr for 1-2 extra ponies.


If you have aggressive mods like a ported head, turbo or SC, then I would defintely recommmend dyno tuning over a mail order chip.
