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.

Hmm, fitted a .8 jet and .5 restrictor, ran it with the threshold above 50% at 1 o'clock and the gain turned almost all the way down... engine just let go. Now pulling it down to see why! Cylinder 3 spark plug is destroyed, roller arms are off the valves on cyl 3 & 4. This was with 100% water.

Which wiring diagram did you use?

Hi, one off this forum, I'll look it up again. I've sorted the gauge, the connector was not clipped into the controller fully. Pulled the engine, the problem wasn't caused by the aquamist, I removed a boost pipe below the throttle body to allow any swarf to be removed when drilling the jet hole, something steel must have fallen into the boost pipe while it was off and on a full throttle run was injested �� I'll get back to setting the kit up when I have the engine built up... 25 years and I've never had this happen, at least it was on my car and not a customers!

The HFS3 is not designed for the TFSI engines, correct diagram is here but for HFS4
