Diesel tuning in Berrima, Cooma or Queanbeyan

Hi all,

I am looking for a reputable diesel specialist who can tune and breathe a bit of life into my '02 Patrol that runs a 4.2 turbo diesel with Dgas fumigation. I don't think it is running as well as it could be and although no expert, I reckon its noisier under the bonnet than it should be. Nissan recently did the valve clearances at an extreme cost and it sounded better for a day or two. The gas made a noticeable difference, power wise, but I think a full service inc injectors and pump timing etc... will help. I am also hoping to slightly tweak the turbo boost for a bit more performance. Not sure what can be gained from the old 4.2 but I am sure it could be better than it currently is. Its has less than 100k kms on the clock. Would also like to hear from other patrol drivers of power outputs..

I am in Melbourne and I am planning to travel northish toward Cooma, Queanbeyan and Berrima in the near future. My plan was to spend a night in Berrima having searched the WWW and reading many ads and other paraphernalia stating I may be pleased by visiting the area, however, reading deeper between the lines of different forums, Berrima may not be the place to visit anymore and I may be just as happy visiting the area of Cooma (now Fyshwick) or Queanbeyan.

Further on that, some info suggests Cooma ain't what it used to be either.

Can members' provide their personal experiences (without breaking any laws) if I should consider travelling to one place more than another OR do I need not travel at all, living in Melbourne, maybe what I seek is under my nose?

I have searched the forum without much success.

Thanks guys/gals :)
