BP kit folks. Question on wastegate plumbing.

I'm currently having this overboosting problem! With ebc off I hit as high as 13.6 @ WOT, low boost setting is at 9.5 I hit 10.6. (I have the 8 psi springs that the installation booklet recommended to install)

Install is the 7.5 Yellow spring and it seems pretty consistent at least in my case that the guage reads 1.5-2psi over the isntalled spring rate. It's done this on me with the 5lb,7lb and the 10lb springs. But my previous problem had several causes and one of them was a small hole in the passenger side wastegate. While troubleshooting all my runs were done on wastegate only. with only the lower wastegates plumbed and the upper open to atmosphere. It only overboosted until I re did all the vacuum lines. After replacing them all the 5lb spring hit 7.7psi consistently. After I got that under control I plumbed the EBC with new vacuum lines. Whatever you do stay out of it until you get past this bump. Piston Glitter looks like artwork but it hurts your heart.
