Two of the hoses, when pressurized at .8 kg/cm2 will open the wastegates, the other two don't. I hooked up the HKS controller like the instructions say (worked fine with int. wastegate t28's). One way the boost will not go past .8, hooking up the two that release directly to plenum. Swap the hoses and it never releases boost. WTF? I switched the cont to external wastegates too. Right now I have it rigged like it's an internal wastegate...releasing at like 1 kg/cm^2. OH...the frikken TD05's kick ass, thanks to twinturbopete!
