o6 gives you a pd engine in a mk5 platform. for mild tunes go for stage 1+ Rocketchip tuning by Jeff 9very refined tuning. If you are thinking you want to go a little more out on it you can go right up to new injectors from a euro pd150 motor, bigger turbo, exhaust, intake, intercooler, and a tune to get you around 200hp. Just note no cams yet...
