Tuning with Safc2 with SBR G-50 turbo?

[Jeff@Slowboy]

I just installed the SBR G-50 turbo on my car with there new cast manifold. Im running the tail external wastegate with 1 bar spring. For injectors im running Fic-650s. AFpr, Walbro 255 pump. My fuel pressure is at 38 wit the vac line connected. My question is at idle my wideband is reading 16.00 and no matter what percentage of fuel im pulling it stays there. I was just wondering if i should turn the fuel pressure up a lil or what to get the car to idle a little richer. Thanks

I would first check for exhaust leaks before the sensor, that would make the gauge read really lean at idle. And would read 14.7-14.9 while cruising as long as the leak isn't that big. Check the o2 housing to DP bolts and gasket common problem and turbo to manifold. What are your fuel trims? My low setting are -18 to -20% out with 650cc. And my a/f is 14.7-15.1

My short term trims were between -5- 5 and long term was -10 - 10. Ill check for leaks 2. I need a gasket for the evo 02 housing and the apexi downpipe i cant find one.

Is there a gasket there now? You should just be able to use a 2.5" gasket from pepboys, advance or autozone. That is what i'm using with no troubles. Becuase of the Evo housing though, the one side bolt hole may need to be trimmed. But you can make it work rather easlily.
