Max Boost On Wrx
What is the maximum amount of boost has anyone used on a WRX. I undestand I should not use more than 14psi, but has anyone use more than 14psi and if so what was the results. Any damages etc.

up to 15-16 psi is safe...after that knock and other bad stuff may happen...i've never heard of anyone's car being damaged after raising boost 1-2 psi over stock..
