Outer Limits 4x4 Board

The HZJ105 with aftermarket turbo started to miss at 2200rpm the other day pulling up a large hill. It also did not 'feel' as if it was willing to go past the 2200 rpm mark. I have changed the diesel filter and air cleaner to no avail. Can anyone recommend a diesel service company in the Sydney area. I am currently considering either West End Diesel or Cooma Diesel. (Yes I know CDS are not in Sydney). West end recommend a fuel aneroid device another $1000.00. Both companies want the same $$ for the service but Cooma do a compression check & tappet adjustment also. I have two brand new sets of Toyota 105 series injectors. Should I just put them in myself, bleed the system and see what happens.
I do not mind driving to Canberra if I get the right job done.
Any help appreciated.

If you are prepared to go to Canberra there is also Queanbeyan Diesel Service. Recently had injectors, timing etc done by them and happy with the job, customer service was excellent. I think Mick is the bloke running the show and was very helpful.
