Actully that figure is easily achieved with the right mods why o why people keep going on about its not achievable I never understand. I am running two golfs at the moment with K03s's and both running over well over 230 on a k03s a simple search on Vortex UK-mkivs will show many others runing the same. Actually there is a chap running 261bhp on a k03s with a Jabba custom map with a printout...
I am talking from experiance and personal cars not hearsay either...
