152kw!! On a gtx3071! I ran 176kw an the stock turbo with Walbro pump HDI intercooler and 3" exhaust. You should be pulling at least that with that turbo. Not familiar with tao's (stao's) turbos as I've never had one but honestly haven't heard good things about them. Once I upgrades to the intense billet RS turbo and 2.5 intake I pulled 245kw on stock injectors.
