Basically, remove the MAF, and during tuning you disable CL/trimming, and use wideband lambda to correct the VE table.
Then for street use, you can enable CL/trimming, or for race use you can eliminate the O2's.
+1 on COS5... it's very versatile (nitrous, boost, SD or MAF, OL or CL, Alpha-N).
COS5 needs a 0411 PCM.

Running EFILive's COS3 which lets you to easily switch between front O2s and SD at any MAP & RPM cell. Used the front O2s for a while with the stock cam but after the blower cam the AFR was all over the place. I could hear and feel the motor oscillating rich to lean... very annoying even with the average AFR where I wanted. Switched to 100% SD and it was so much smoother and gained a few mpg not that it matters.
