I have. I have been asking around but no one seems to be able to explain the actuator and so on.

I ended up checking the actuator...A -22 standard one. Preload was set fine. The pipe wasn't loose on it when pulling. Tight.

So I got a -31 off my mate. It was set to same preload...and was boosting 7psi strait away. Bleed valve was opened and was messing about to see boost rise and it did to 9psi before my bonnet cable snapped and I couldn't be bothered to finish testing. It was however spiking to around 12 psi and leveling out to 9...?

So why does a -31 actuator work better than a -22 if you are going to use a bleed valve? I don't understand this and can't find an answer.

Thanks
