Any ideas of what is going on?
I have the cobb stage 2 reflash and just put a vf30 and sti injectors and with the stock turbo i had on it would hit 17.5psi and now I did not push the car too much but now only hits 10psi with the vf30, is there a reason why this is happening?

Your FBC hose, and/or restrictor isnt on properly, or its borked.

seems normal, i have the same setup and everybody i know with stage 2 get around 15 psi.
Also how long have you had stage 2? It takes a couple of days for the ecu to learn. WILL |

I bet the vac 'T' isn't connected properly on the turbo, or the 'pill' is missing.

I just tried a few things first i clamped off the hose going to the solenoid and nothing changed then i undid the hoses to the accuator on the turbo and it hit full boost. So why would that be. Do i need to get a boost controller now that i put a bigger turbo on? Because i thought the computer can do it.

You should put the vac hoses off the stock turbo on the VF30....make sure that the hoses go in in the same way...there is a little 'metered orifice' or 'pill' in the one that goes on the turbo nipple. That hose with the 'pill' MUST be in place and in the correct place or, many times, symptoms such as yours result.
