    some guys have boost creep problems due to the small waste gate valve,, it looks like u still have to buy the wastegate actuator

    Thanks!

    Are you saying that happens with all stock-style swingvalves on T3's, or this specific product? Do you think it would be worse than stock?

    The hole for the internal wastegate is in the turbine housing, that housing just has the swing valve with the puck that covers the hole. With small turbines more exhaust volume will need to be bled off around the turbine wheel to keep shaft speeds (or boost level) in check so a larger wastegate is needed - that's where the internal WGs fall down. A small engine with big turbine(s) and high boost needs less WG flow than a big engine with small turbines and low boost.
