Hey Dude ,
If you do want to start with a bleed valve , use the simple Turbosmart one ,
they are "Gated" which simply means that they have a 5 psi check valve in them , which means no wastegate creep til atleast 5psi...... short version = better throttle response
If you use their "Single stage"(stock & Hi) one & your car is an auto you can use a relay to the Power/Norm/Snow button to fire it ( I did ;P) so when the auto is set to Power , the boost is set to High! All good. :burnout:
