So currently I've got a j-spacer in front of my downstream O2 sensor for CEL purposes. Can anyone confirm that the ecutek tunes for this gen will eliminate the CEL if I pull the spacer? My car is down due to a tire issue so I figure I might as well pull the spacer now(which I think means taking the header back out unfortunately, super low clearance with that spacer) as I've a tune kit coming in the mail.
