I've currently got a Brenspeed SCT tune, but I am soon installing some 3.73 gears. Is there a way to manually adjust for these new gears using thetuner? I didn't see any options for manually adjusting certain parts of a tune, just to upload the 87, 89, and 93 tunes that I bought with the tuner. Do I need to get a brand new tune from Brenspeed?

Same goes for disabling the rear 02 sensors. I would love to be able to do that without purchasing a new tune.

When you are installing a tune on the car with the SCT, it asks if you want to change any parameters or something like that. Hit yes (or select button i think?) and scroll through the editable options - one of them will be gear ratio. Then you can just choose 3.73 from the list it gives you and continue reflashing ur car with the tune you already had.

Sorry, but i don't know what to do about the o2 sensors, i don't know much about them [&:]

You should adjust your tune when changing gears higher or lower with any tuner.
