boring..
I suggest wind it up till it pops
on the serious side of things, I think that so many people have so many different opinions due to their experiances in this regard all with different set ups which makes it kinda hard to judge what you should be doing.
When my issues are all sorted, I'll be setting it to 13psi for my stock turbo and it might even be worth you looking at gettin a 33 turbo for nto much at all and throwing that on!!! (but not mine.. hahaha that has had a beatin hahaa)
