Over boost problem is fixed. Didn't need the new springs. Just had to open the top port on the wastegates.
It holds a steady 8psi right now. I know I was going for 10 but I think I'll stay right where I am. I didn't notice any clutch slippage with the lower boost so I think I'll keep it there until I get a boost controller and I'm ready to upgrade the clutch.
I told you all, in the beginning, that I knew enough to get myself in trouble.
I will be running the open dumps for a little longer. I talked to Sam and even though he feels that my problems aligning the pipes aren't being caused by any problem with his product, he is sending me a new set to try.
Throughout this process Sam has displayed top notch customer service.
Thanks for putting up with me Sam!
