okey today i was driving back home from the store n i felt my car not giving full power when the turbo spools up..
then i let off the turbo a lil soo its reading 8psi n its start pull like so...the turbo starts skipping(studdering) when pass 10 psi n my suby goes no where..
mods i have done:
sti vf39
sti injectors
sti tmic
walbro fuel pump
injen cai
i have tbe but got ref soo took it off
everything else is stock
i cant figure out the problem..
i firgure the turbo is blown or going out
any kinda info would help a lot

 

Is it tuned or does it have a AP? Perhaps a hose has come loose or something like that or may even be pulling timing or something similar.

I had a similar problem when I would hit high boost and the turbo would shudder. Ended up being a loose coil pack. One of the bolt worked it way lose, just got it tightened and all back to normal. not sure if this helps but have a look see and check you coils.
