Thoughts please:

I've finally got my corrected TT hybrid coming back and I will be looking to get it fitted early in the new year.

I've got a hunch that my current injectors or rail are not quite 100% so am considering, seeing as I will need to get the turbo mapped in to run an effective St3+ on stock internals, whether to bite the bullet and get a new rail and some GG's. This will give me the basic set up when I (hopefully) move on to forged internals later in '18 and rule out any possibility that they are / have been causing lean running when running the St3 map.

Has anybody done GG's at 300ps? I understand they are nice to map and have a good spray pattern, all things that sound positives, but do they work ok at this level or are they simply oversized? I don't want to get messing about with swapping in more stock units only to change them.

FB2 was running a Maptun stage 4 map (and later a Noobtune stage 4) with a 19T #6, Maptun IC, Abbott delivery pipe & cobra, Abbott 3" system, T5 cams and 465cc GGs. Around 315-20bhp, 450Nm.

300 is pushing the stock injectors, even with a 3.5 bar FPR.

GG's or Bosch 550cc Blue Giants are both absolutely fine (and quite nice) to map. No problems with idle or minimum injection times.

Right - so it looks like we have a plan :-)

Having searched a bit deeper on on the forum I have found a few other threads suggesting that in reality the St3 would be better with GG's rather than doing the 3.5bar FPR. Its a question of initial costs but I never got my St3 to run well and have yet to find the underlying issue.

New shopping list - new fuel rail (just in case we have a problem there) a genuine 3.0bar FPR (as my original one got chucked at the garage when the 3.5 got fitted!), some BG's or GG's (Bee Gees's??) and some spacers.

Some info on how it all fits together and the spacers used, if any would be much appreciated.

Just started to search on the Blue Giants and it seems they are the Astra VXR injectors and flow another 30cc @ 470cc!!

I asked about these earlier this year or late last year and didnt get any response.

Do Green and Blue Giants both need a spacer to fit correctly?

I cant see that Maptun have theirs listed any more - is the M8 nut or washer trick still the only other way?

I thought the VXR's were different and we didn't have any battery data for them, that's why we couldn't use them 100% correctly.

The 550cc Bosch ones i'm referring to are part number 0280158279. The only issue that used to be with these is they have USCAR connectors.

Right - so GG are a direct fit and 0280158279 needs a modification to the connection?

Searching generally on Blue Giants shows up an injector for the Volvo 5 pot and as a performance upgrade for VW's tagged the EV6 470cc.

Seems the 0280158279 is only easily available from the states so for what I need (sub 350ps) I would think then that GG would be adequate?

Any comments about the spacer / washer needed on the GG's? I can't see that Maptun do their offering any more so it will be down to the washers / nuts solution but I would like to know what exactly to get.

Also, are GG's direct plug-in or do they need any adaptor?

On the 9-5 GG's should be the same connector. Isn't Simonty on here selling a set off his stg4 9-5? You might get the fuel rail as well. And the spacers.

You have read my mind!

I have literally just seen his ad and bagged / requested all that gear :-)

Amazing what you come across when you search on 'Stage 4' ;-)

I have been running Genuine Bosch GG since October 2016.
It is a plug and play job as far as connectors, and all you will need is some washers and two longer (10mm) bolts.
All I did was to unscrew one bolt take it to a hardware store to find similar ones with 10mm more length and matching plain washers. The installation is easy as long as you can hold the washers together. HINT!!!!! Tape them together!!!!!!!
You can remove the tape afterwards.
I have never had any problems with them working or performance wise and this is also thanks to Karl's (SAABNOOB WIZARD) tune.

It is by far a better and safer option than a FPR in my opinion.

If I understand correctly, you need 10mm of washers for each side as the bolt needs to be 10mm longer. A nut or two would also do the job?

Yes sir. Exactly.
However washers give you more room to play length wise and are more precise as their surface is more even than that of a nut.

Good point. Washers it is.
