Gaz084 Member 29 Member For: 9y 8m 21d Posted 09/12/23 10:34 PM Share Posted 09/12/23 10:34 PM Hi Guys. I have just purchased one of these with a 45mm turbosmart hypergate. PULSAR External Wastegate Ford Falcon FG/FGX XR6 5-Bolt Turbine housin – Pulsar Turbos Australia The wastegate is set from factory with 14psi of spring pressure...currently the car is tuned to 12psi,can I set the wastegate to 7psi by removing the inner spring and still drive around while trying to keep it of boost until I get a tune done or should I just wait until im ready for the tune?

Spring pressure is minimum boost pressure So removing a spring to make it 7psi, will suit your current tune. The only concern may be that your tune is using the stock/OEM wastegate, so you might have issues with overboost, so best to not hammer it on the way to the tuner.

I had This current engine rebuilt from an overboost ,so I am a little nervous it will happen again....would it be worth while getting an over boost valve or am I just being paranoid.

You can file it a little bit if you want or just run it as is. As long as it isn't touching the turbine housing it'll be fine. Link to comment Share on other sites More sharing options...

The more boost a turbo has to make the later it'll reach full boost and various supporting parts also make a difference, so there isn't always an exact answer.
