i wasnt expecting any performance gains from this, but i think it has. above 3K revs it seems to pull smoother, and the sound is wicked! very quick delivery.

Delivered in a good time frame from purchase. Installed and noticed a great power increase and the Fiesta ST preforms much better! Bang for buck...nuff said!
