   I am currently doing a GT2871 turbo project on the S3 8L. I would like to know which PSI springs people are using in the wastegate and bov/diverter valve with this setup.
   
   Current setup is...
   
   Rebuilt engine with forged rods.
   ATP cast manifold (T3).
   ATP turbine housing (0.63 A/R).
   Custom 3" down pipe.
   Custom 3" catback.
   Wagner intercooler.
   Forge diverter valve.
   38mm Tial external wastegate.
