OK so finally got my first datalogger in, log'd a run and seemed to prove to myself that my car is running to lean? I changed all my spark plugs and they were all white, and smelled bad (hence a lean condition?) If this is so, I'm having a hard time figuring out why. When i changed
the plugs and decided the car was running lean, i even turned the boost down to 10psi just to be on the safe side. The log was also taken with this same psi setting.
Mods:
b16g Turbo
550cc Fuel Injectors
Walbro 255hp fuel pump
ACT 2100 Clutch
2.5" upper intercooler pipe
MBC
2.5" Bushar Turbo back exhaust
JDM 6-bolt
Here is the log 3rd gear pull / 10psi.

Any ideas on how to fix this, not feeling real comfortable driving the car with that kinda knock. I own my own business and bought this car because i enjoy working on it, and want to eventually race it. Money is not a problem within reason. Although I'm a complete newbie and have buried myself into research on DSM's, thanks in advance for any help you guys can give me.
