sorry to butt in!

is there any difference at all between these two methods of boost control?

- compressor, straight to actuator. Boost set via actuator spring.
- compressor, straight to actuator with bleed valve.

What would differ between those setups?

I realise running the bleed valve means you can use less pre-load on the actuator therefore lengthing its life, but other than that any differnces?

I'm guessing the bleed-valve setup would have a slower boost climb rate (due to wastegate creep?)....whereas running straight to actuator should let the boost build quick and then hold there?

ty!
