Hi guys, my S2 is only boosting at 2psi and i need to increase it to the standard 7psi. Am i right in thinking that i need to wind the actuator rod in? Its overfuelling at the moment before anyone asks
Hope someone can help, its slow as hell at the mo

 

First look how much turns left on actuator road, I mean look how much is he short. Or send us pic. Because maybe isnt problem in actuator, like was on my car before. manuals said 1 turn is 0.2 bar.

 

There is a threaded sleeve over the actuator arm wind this in towards the actuator to shorten it so its harden to put onto the wastegate arm. This puts more pre-load on the actuator .

Trial and error till you have the boost your looking for

 

was it ok before? if this has gradually happened then you need a new actuator otherwise you will never get it to boost properly

 

I would get it set up properly... got to be cheaper than guesswork prior to the engine going *BANG*

 

It's OK adding pre-load to your actuator, but what if you do that, make your 7 psi or whatever, then in 6 months time when you've forgotten about it, you find a split hose, fix it and end up with 15psi and a melted engine?

 

Dont worry Christian i aint a dumbass Just wanted to try the actuator rod to rule out a few things.As it is, i wound the rod and it made no difference

 

i got the smae problem
