Hi all,
The short version...I have a supercharged 08 (LS3) Corvette that I had tuned by a "professional". The car runs fine, but I'm having trouble getting it to pass the readiness checks for emissions. Seems the rear O2's have been tuned out.

Since having it tuned, I've moved roughly 15 hours drive away and having it retuned isn't an option. Not only the long drive, but discovered my tuner had done some shady things so I refuse to go back. (locking my ECM, selling me EFIL and wideband O2 setup, then trying to charge me to unlock it....for starters) Besides, I'm more of a DIY type and I'd rather...ya know...DIY.

I have the v2 setup that I've slowly be learning, but I can't for the life of me get those rear o2's back in service. Even temporarily just to pass the emissions check to get my registration renewed.

Any help or advice would be more that welcome and appreciated. I hate asking, but I'm at a loss and need to get this sorted on my daily driver asap. Thanks so much.
