So I am sure that there is a thread that already answers this question, but after digging and digging I finally decided to just ask. I'm looking to know the max pressure I can run on the stock turbo, with practically no mods. only have a kn cai. Wondering the max I could safely push, and how you go about doing the adjustment. thanks for the help!

 

23.5 psi. hp tuners tuning software.

 

anything over 24psi is just pushing hot air...fully bolted on 93 gas will get ya around 320whp/380wtq on an aggressive tune, running e-blend will get ya more midrange and about 20-30whp more....
