just tuck up the wires and your good to go. You dont have to get a tune for the rear O2's, it'll just throw a code and set off your SES light. A tune would get rid of that, and would also get ya some extra ponies.
buy some o2 simulators or get the pcm tuned. it is not good to have the check engine light on and driving with it all the time., because if some other codes decides to go up the check engine light will already be on and the guy would think everything is ok.

Yes but putting on LTs has changed our Air Fuel ratio also and you won't see a decent gain until you get a tune. Get a tune, you won't be disappointed. Your car will be better overall with one.
