How much boost can the stock turbo, fuel pump and injector can hold up??
I just wanted to know, because i will insatll a manual boost controler, how much would be safe??
I thought if 7psi(stock) then I could raise it to maybe 10psi
its that about right??
what if I put a preassure swith with an aditional injector, how much then, 12psi??
thanks for your help!

I am running 12psi and had a dyno. The car runs rich under full boost. This means that it can handle more, perhaps 14psi. I have modded my airflow meter and running stock ecu.

I would only run this boost during dry road conditions, waste of rubber otherwise.

Modding the airflow meter is a bad choice. From what I have seen over 3/4 of the people that have tried it have destroyed it. Besides that you don't get the fuel curve needed to run beyond 12psi and that spells trouble.
