I'm so glad I bought a rt when they were available. It's been over 2 years, I haven't even touched it besides the basic tune. I can't believe I waited so long. I've got like a billion questions that have probably already been answered. I didn't even think about getting a wideband in my car until now, I always saw them in customer cars and figured the idiots just liked staring at the things because I KNOW they weren't doing any tuning, I thought the only way you could get a tune that was safe was to go to a dyno and stuff. I feel like a big retard for not reading into it, especially considering I work on cars for a living. We don't really do any tuning though, just fix what is wrong under warranty, so I never got to involved. My downpipe has a bung in it already, but I thought it was too far away, then I read more into the wideband and I guess it's in an alright spot, right after the flex pipe. I'll shutup and read some more now.
