Yeah they are pretty good (Aussie guys). When I first got my EC5A V6 VR4 here in Hong Kong there were zero options available for tuning. RPW did me some upgraded turbos, camshafts, headers and did some headwork (porting valves and springs) for me. Not cheap but quality was pretty good other than the turbos. If I ever did something like that again I would go to a turbo specialist to get the turbos done. They have some interesting stuff on their site.
