Stop looking at the open turbos in the Import Tuner mag's thinking these are actual road driven cars... Plus you say there is "so much pluming." Ok, if you have a 7m (assuming you do being a 91 unless you have a jz swap then I am not as knowledgeable) it runs the idle speed controller, factory blow off valve, and positive crank case ventilation... and that is not very much... there are different things you can do with the positive crank case ventilation I have seen and know some about but have not attempted yet. last words, AIR FILTERS ARE MADE FORE A REASON.

No, on the stock CT-26 you'll hit fuel cut around there; On a higher flowing turbo you'll probably hit a couple psi lower without additional tuning. Without knowing the specs of the turbo no one will be able to tell you precisely and there are other factors which play a significant part such as the intake setup (intercooler and plumbing), ambient air temps and humidity, etc. I'd start at 10 and see how it feels, if you want to push it past that then go to a performance shop and get a single base line run with the AFR graphed to see how the mixture is looking... it if's good try out 12 and keep it there for a while.

Have the fuel pump and filter been replaced?
