It seems to be that the stock motors have handled upwards of 20psi without much problem if you use very good fuel and have the tune spot on. There is however no room for error at that level.

The main reason I started this thread is because I am running 9lbs of boost on my stock 5.3 and I want it last until I do the LQ4 and 4l80e but it feels pretty good right now!
