Well I am using an external wastegate. It is a godspeed one and works pretty well. The BOV is a RFL knock off one. I already shimmed it with 2 washers. It may still be the blow off valve leaking though but like I said it will hold 7psi fine from like 3krpm to 5.5krpm then it starts to bleed off down to like 6psi. I have been very busy with school and haven't had time to leak test the system. Hopefully the clutch goes in today and I can also leak test today or tomorrow.
