A lot of people do it. Just don't do it all of the time. As you know given weakness of our bottom end, its crap shoot each time you do it. I've gone up to 14 psi with 100 octane fuel several times. Most of the time I drive around at stock boost. Right now my boost settings are stock and 10 psi.
61,000 miles on the car with the original clutch and lsd. What works for me may not work for you. Boost wisely and at your own risk!
