Blew Out Intake Plenum Gasket

I tested my system for boost leaks but this was only up to the intake horn. When doing injectors I found out that I blew out my gasket on the intake plenum - and the stock/standard gasket is apparently prone to this occurring when boosting over 50 psi.

Got the gasket fixed up and it essentially doubled my boost pressure in daily driving. Didn't realize that there is a metal gasket one can get from Cummins though. So I'm going to get this to ensure it doesn't happen again.
