quick question.. where do you guys w/ E-cutouts have your O2 sensors placed at? before or after the cutout?

I was thinking for tuning and driving purposes, you need it before the cutout so the o2/wideband can read the Oxygen levels from the exhaust before it is expelled out of the cutout when open.

Mine is currently positioned after the cutout since i made my DP before deciding to incorporate a cutout to the DP.. Now i'm having concerns about it because when the cutout's open during part throttle, or even idling, the O2 may be getting inaccurate readings.. I may have to weld a new bung up closer to the turbo and before the cutout opening..

please chime in on this..
