Some people are pushing 16psi with JB4 in

Stock is about 11-12 psi in sport mode. 2psi less in comfort
Thanks! That's good to know.

I saw some information on threads and forums about how these turbos were tested and were pretty solid. I think the choke point for them were around 25-26 PSI. It was handling PSI from 18-22 easily.

I wonder what limits others have pushed it too
