It feels ok. On coastals dyno im at 12.2:1 and the gauge is 2nd to last bar. I know this is a ghetto way of tuning, but Im trying to get the a/f back down to there @ 15psi. It's going yellow/red @ 5k rpm in like every gear. It's strange.

i would deff upgrade to a walbro 255 fuel pump if you can spare the cash, i have one on my dastun and its a smart upgrade.
you still have a brabed style fuel rail or a o-ring one now?
also how do you like the SDS? i was gonna get it but i got the microtech instead... im not sure if it was the smart choice for the extra money...

the narrow band disco light O2 sensor gauge is junk. they can be somewhat calibrated....but the refresh rate on them is so slow you cannot see true readings.....and the readings you do see cannot be trusted.....the greddy guage I hear is pretty good as asubstitute....it uses its own wideband O2 (you install abung from what I gather....and I like typing bung cuz its funny)....
You are better of with an exhaust gas temp gauge.....it will let you know when you are going lean easier than those air fuel meters....

a baseline dyno is a one shot deal...this sounds more intermettant(sp)...so it could him an idea of what he is doing when it goes lean....and its a good thing to have in a turbo car anyway (well..living up here with huge weather changes it is)....

It sounds like a fuel pump.... atleast that seems to be the issue with most turbo cars.......... I learned that the hardway with a turbo dodge charger.

Get a baseline or maybe 2-3 runs... work out problem.. set it and forget it...
