I know there are a couple of very old threads on this topic, but does anyone have any info or experience on tuning the 1.7 puma engine?

I have one in a mk5 fiesta, people have said it’s possible to reach 180bhp with head work only??

any ideas what exactly would be needed to get to this?

or any guesstimates what bhp would be made with cams, induction kit, 4 branch and a remap?
