I have my 6psi graph at home, will upload when I get a chance, however I had some seals that were leaking. Got that all fixed now and I will re-upload a graph when I re-dyno.

Went to Z-max dragstrip and unfonrtunately was only able to run on street tires, I'm looking into purchasing two rims & some Nittos (or similar) to have some traction better than street tires.

HOWEVER, being now at nearly 9psi (woops) thanks to an 11.7psi spring; the car absolutely halls *** when boost comes in. AFR is at ~11.5, 18 degrees timing. Stock bottom end, stock internals (woops), lol.

trapped 119.26 MPH in the quarter.... lets leave the rest up to talk.
I then went back & looked at my log.... and looks like I'm going to be due for some changes in the close future.

Duty cycle up high, averaging ~82~85. Don't pay attention to some of the numbers, my exhaust clamp fell out towards the end of the track.  

I'm going to get a chance and test & check these values shortly just to double check. I will probably pick up some 50# (actual 57.7#@58psi) injectors or 55#(actual 63#@58psi)
and have them flow matched locally also.

If you look at the LB/MIN of airflow.....well this little 60mm garrett journal bearing turbo supposedly maxes out at 63LB/min of airflow...

I plan on the injector &/OR pump upgrade to a Walbro 340 possibly, installing my IC fan & switch, and tearing my turbo apart to investigate & inspect sometime between now & January 2010.

If the turbo is ok or there is some turbo I have found that is WAY better, perhaps ball bearing & just a tad more airflow, etc. I will probably upgrade & get the exhaust housing ceramic coated, wrap all I can to keep heat in and re-dyno & re-visit the track
