Those figures are more likely with a custom tune

I fitted some of those high ratio rockers to my old Ecotec and yes the difference is noticeable but as above would be better with a tune to complement ur exhaust etc as well, just a cat back exhaust isn't gonna make much difference u really want a set of pacemaker extractors to go with it

Can have a top end supercharger conversion for pretty much the same price... Just saying.

I noticed a difference too , when I fitted them to my VX , but I had a few other bits as well .
