Among others I used to get the P2097 code on my LS3 Camaro that had similar mods but a big cam as well. The problem was it often was one cylinder bank and not the other. This led to timing and other new signals being pushed to the ECM and subsequent running/missing issues. Needless to say I did have it addressed and was fortunate the tuner for that car was close by. The fun part about these largely bullet proof LS3's is the learning experience. Get it looked at, fix the problem, learn how to self manage the beast! In my case it was an anomaly that didn't have a true cause other than the tuner going through and retightening every single connection and verifying proper signal strength was coming from the various data collection points. My guess is the O2 sensor was not happy (in my case that is...).

 

Thanks! I'll wait and see if it pushes out any other codes or this one again, I guess, then call the place that tuned it. Seems like that'd be the best place to start. Based on the reviews I'd like to take it over to Livernois (same distance, opposite direction) but probably best to take it to who did it in the first place.

 

I had Livernois tune on my GTO and on my 2014 SS before I had it supercharged. Livernois is easy to work with when you purchase the tuner from them; in my case I purchased a used tuner from another SS forum member and the experience was not as good. Essentially my ECM was bricked by their handheld tuner because it was older (needed updating) and I did not purchase from them. I've had good success with Livernois in the past but not so much the last time. I would recommend taking it to them as anything to do with updating your tuner, because you are not the original purchaser, might be an opportunity for trouble.

 

...plus I don't actually have the tuner from my car. Guy traded the car in to the dealer and did not include the tuner device.

 

That's not good. Be prepared to spend some $$$$$

 

Yeah..i figure I'm going to end up buying their tuner then having to pay for a custom tune. Sound about right?

 

I'd count on it!
