Are you going to create a ticking time bomb, that is the question. My opinion for what it's worth, which is'nt much is it will all come down to how you drive it. Flog it and somthing will give sooner or later, even on standard boost. I've been running 10psi for about 3 months and I know one thing, you will tend to drive alot harder when you have the extra grunt. No problems for me so far.
