I've tried moddedmustangs and mustangforums and didn't get any answer. All I need to know is if the basic strategy tune automatically turns your rear o2's on. My exhaust is fully modified from the headers back and I have no cats. I'm using antifoulers on the o2's. I know I need between a half and full tank of gas (from what I've heard), but I need to know before I start trying to set it if the strategy tune turns on o2's by default since our cars don't have the option to turn them on with the X3. I'm overdue by one day now which isn't a big deal, but cops around here are pretty bad with inspections (ask me how I know). Any help would seriously and greatly be appreciated.

Stock tune has O2s on. If u by basic strategy the SCT strategy, that would have them off, 99% certain.
RTM for the driving cycle. If no owners manual. Use google or search here for it.

Okay thanks! My only other question is if premium will mess up emissions on an 87 tune. I filled with premium, but I found an old bama street tune that was set to have the rear o2's on with my intake. If ai run that tune on 93 octane, will it screw anything up? I'm sure I won't kill my engine on a tank, but I'm trying to do this as efficiently and quickly add possible so I don't want to waste any time trying to figure out how 93 could possibly not set my o2's for inspection on a tune for a different octane.

If you're in a state that performs a visual check for cats, you're screwed no matter what you do with your O2 sensors.
