Thanks mate. Sorry the delayed response, don't really frequent on here anymore.
Have found the turbo to be great for what it is. I'm running the bush bearing version. Was previously running the .86 twin scroll rear housing which made 420rwkw on ~26-28psi. Response was great. We've recently changed the setup to a 1.01 rear housing to help with getting more heat out as I kept melting the diaphragms in the gates. As a result I'm currently making 370rwkw on 22-23psi (need a new boost controller) and I'd say a few hundred rpm laggier, but much nicer curve coming on. Will put together a big update post eventually, but feel free to pm me if still looking for info.
