I have the APS TT kit on my 350z and installed the Forged Performance WGAs on the car but cant get them to hold more than 6.5psi of boost? I have the 5-10psi springs in them and would like to be running at least 8.5-9psi of boost. We tried running both the boost controller from aps as well as a turboxs boost controller and cant get the WGAS to hold any more boost. Any ideas of what could be causing this? Maybe the length of the WGA arms?

Thanks Everyone

 

You mean Forced Performance? Is this the standard APS kit with internal wastegates? If you have a boost controller with internal wastegates, it should be able to hold up whatever boost you set it at unless exhaust backpressure overwhelms the wastegate.

 

I've seen a couple threads on this before.. and it was a matter of using the other springs.. and Raj is right.. you're confusing the names of the companies... Forged Performance doesn't make that wastegate

edit: i thnk the place is called Forge Motorsports

 

Its these wastegates

So i might need to just order stronger springs for them?

i had the same issue with my HKS tt kit dual gt2871r garrett turbos. i was only able to boost 8 psi which gave me 395 on the dyno dynamics. i m not sure if i only have to change the springs or the whole actuators???
