ok.. dyno tuned today... graph is below.

problems: HUGE boost falloff and turbo lag problems... redline boost was only ~6psi, midrange 9psi. Turbo wasn't spooling full boost till almost 4000RPM, and fell off really badly at 5500RPM...

mods are in sig.

Well, it could be your tuning...

What did tune your SAFC to?

Do you have a chart of your AFR?

I made a thread in the 2nd gen forum about the problems, but thanks

AFR chart isn't really necessary, they were 10.8:1 EVERYWHERE after 5psi.

10.8:1.....

Geez, little bit rich?

That could be hurting your boost.

how new are the plugs?

I pulled the plugs and cleaned them the day before, trailings still looked brand new but the leadings are starting to show some wear... maybe 6000 miles on them?

they were in the jspec when I bought it but had NO wear on them at all.

You didnt answer the question...

Why did you tune so rich?

yeah seriously 10.8 you can't be using all that fuel, your milage must be crap, and your egt's must be insane.

/I/ didn't do the tuning

milage seems to be fine, honestly though I don't pay any attention to it.

fixed the boost problems mostly... installed I/C sprayers... maybe I'll add a few more PSI.
