Just upgraded my custom rear mount, with a tial 44mm wastegate. Spring was a 7.25 but I only see 4 at the engine . do I need ti get a 14.5 to get 8 at the engine or what are any other rear mounts running to get around 8 psi. Also put in a tiall 50mm BOV with 11 psi spring. Under light boost/ letting off I still get the rattle snake sound, Car pulls 21" at Idle should I try the 9psi spring?

I'd get a manual boost controller that way you won't have to play guess and check with the spring.

Run the wastegate boost reference from the intake manifold instead of the compressor housing.

thanks for the idea's I'm gonna get a manual boost controller. But that was not the problem. I was thinking a 3.5 psi drop was too much even with a FMIC so after checking everything out, I found I left a compressor cover bolt off,because it didn't clear my oil resovoir. Problem was that the bolt hole goes in to the compressed air. Of the Six bolts on the cover this was 1 of two that go into the pressurized air.

If its any help I have the a44mm tial WG too and I used a 2lb spring to make 4lbs (front mount), and yours being a rear mount might make it less pressure to push against the spring so you would need a less spring to make more boost. I dont know, just an idea.
