Today in hooked up my SAFC and i did the setup and she fired right up! Just a couple of questions!

Will it be ok to boost 10 to 12psi on a stock turbo? I also bought some 720's that i will putting in soon for the extra fuel i think ill be needing.

I have a 3 inch exhaust, FCD, K&N, ported wastegate, and i have a M300 wideband i plan to tune with.
Thanks Steve

mmm 10-12 psi should be fine, im unsure but i think... do you have a ported wastegate? and what fuel pump?

you can take it to 10psi without any changes relatively safely but 12psi on the stock turbo is about all i would recommend.

once you get the wideband on it you can richen up the fuel maps and then begin to bring them down by monitoring the wideband and tuning it for approximately an 11:1 AFR for safety when in boost and about 12:1 under normal accel out of boost and 14:1 for cruise.

of course overkill is better than underkill so install the fuel pump and 720's before upping the boost though i would say almost positively the stockers can handle 12psi on the stock turbo.
