injector cleaning/flow testing in adelaide

[natho]

hey all

has anyone had their RB injectors cleaned and flow tested in adelaide with good results? if so, where?

every set i've had cleaned (both n/a and turbo RB30 ones) have come back OK and a few months later started leaking internally.

i have yet another set of original ones i'd like at least flow and leak tested but i'm not sure where to go, i dont bleieve most of the places here do a good enough job.

Thanks

Nath
