Dump valve spring
#1
![Default](https://www.scoobynet.com/images/icons/icon1.gif)
I've bought a new atmospheric dump valve from forge and I'm wondering if the spring supplied is a bit to strong. I'm getting a lot of turbo chatter a low boost levels like the valve isn't opening enough, but It seems to work fine when the boost builds up. Just wondered if this was normal and if anyone else had a forge valve and what strength springs they were using? My car is a 95 wrx running a maximum 1.4 bar of boost.
