2006 Golf GTI 2.0 TFSI (BWA Engine)

Hi I've had a search around but I'm struggling to find info on jetting and what restrictor to use for my car. I've fitted an HFS3 v3 and have only got the green harness reading F-IDC currently, no failsafes wired yet.
Where can I find out the capacity of the injectors? I've tried looking for info on them with the bosch part number and vw part number 06F906036A but no joy.
Also the gauge is only showing the 'S' dimly which brightens when revving the engine but I take it I need to get the right jets in first.
Any help would be greatly appreciated!! Thanks.
