Ok so I just got the thermal RD 3inch installed and Im loving it , the sound, the way the car pulls everything BUT...


now my 7-9psi spring in my turbonetics evoultion wastegate boosts to 10-10.5psi. I have the Apexi AVC-R boost controller and I want to boost 10lbs(daily) not 10.5. Any way i can get this done considering that the boost controller wont let you boost any less than the spring in the wastegate allowS? where can I buy a 5-7psi spring?

I want to basically boost 10lbs as fast and hard and early in the rpm band as possible but dont want it to be spiking to 10.5 daily.
