Im currently running a stock map sensor but the car seems to want to boost more than 11psi but cuts off. I also installed a mannual boost controller which doesnt seem to be working as i tried to get it to hold boost at 8psi. Its on a stock b16a2 if that helps.

 

Take a vacuum/pressure pump w/guage, hook it directly to the wastegate, pump, and see when the shaft moves. They tend to open slightly early, but the bleedoff keeps them shut long enough where it doesn't cause much lag. Otherwise...if it's installed, whatever level it holds at (before boost creep, if any) is the opening pressure.

 

I dont have a pressure pump as stupid as it sounds. Is there no other way/ do tou not have a rough idea of how much as it wants to go passed 11psi. The turbo is mabe by garret

 

you have a stock map? it cant read past 11.3 psi or something like that and it might be causing you car to wig out, not exactly sure though

 

I know this, i just need to figure what spring is in the actuator. Can anyone figure it out without using a pressure pump
