The stock turbo will probably get into the low 13's , yes... You'll definitely need a bigger turbo , and injectors , and exhaust , to run 12's.
The only problem being that the T-25 runs out of boost ability too quickly , since its just 3.5 psi short of being maxxed out , already. I'm planning on swapping in a old DSM TD05H (14B) with a lot more CFM capability....that'll MAYBE get 12's.....
I know people with almost stock (except boost-controlled and bigger injectors) DSM's that can run 12's , even at this altitude.......
