Hi
I just finish install the turbo 9 to my evo 8, did a couple full and it hit 25psi even with my boost controller all the way close. The turbo 9 came with the 25psi forge waste gate, could it be the problem?

 

It is exactly your problem.

 

I am not up to speed on the Forge Racing actuators. Are you sure that it isn't a Forced Performance 25 PSI actuator?

At any rate you can try adjusting the length of the actuator rod. So that it just slides freely on and off of the flapper valve pivot arm's peg. Do you know what I am talking about or not?

 

Thanks

 

Yes it have a forge waste gate 25 psi, before I install the turbo 9, my evo 8 hold steady 19psi.

 

So if I want to keep my boost around 21 psi I should go back to the stock waste gate?

 

yes, you need to go back to stock. actuator s/b 1/2 hole stretch on to wg actuator pin.
