Hi all,

Is it normal not to have boost until 5000rpm in First? When I change to second the boost starts building at 2800rpm and is fine!
Has it something to do with loading of the engine?
Also I am looking for a new actuator as I found that mine was creeping, (bolted wastegate shut and found boost came in 200rpm earlier)
What actuator would you recomend to run 25psi? I have no amal valve so this figure needs to be controled machanically via actuator spring.
I looked at the 34 actuator but it says it starts to open at 14 odd psi, can this be increased by putting more preload on spring?


Thanks for all advise, Cheers. Tim.
